Text of the manual
The following late-breaking information supplements the HP SureStore NetStorage User's Guide and online
help. If information in the User's Guide conflicts with information presented here, the information in this file
should be considered correct.
OS Upgrade
OS Version: After upgrading from the original version of the OS (build 81) to version 3.3.x.x you cannot go
back to the original version without risking data corruption. If your file volumes are very large, the upgrade
process may take considerable time to complete. The progress of the upgrade can be seen on the HP
NetStorage 6000 LCD display located on the front panel of the unit.
Administrative Password Challenge for Internet Explorer 5.5: When upgrading from software build 81
to version 3.3.x.x, you may be challenged for an administrative password whether or not you set one
previously. In order to correct this problem, you need to:
· Clear your local cache
· Circumvent the web proxy cache
To clear your local cache and circumvent the web proxy cache:
1. Open Internet Explorer.
2. Select Tools > Internet Options.
3. Under the General Tab, in the Temporary Internet Files section, click Delete Files.
4. In the confirmation dialog box, click OK. You may optionally choose to delete your off-line content
stored locally at this time.
5. Under the Content Tab, in the Certificates section, select Publishers.
6. Select every occurrence of Hewlett-Packard or Hewlett-Packard Company, if any exist, and click
Remove.
7. Click OK.
If you use a proxy server:
8. Under the Connections Tab, select LAN Settings.
9. In the Proxy Server section, check the box to Bypass proxy server for local addresses and click
OK.
10. Click OK again to close the Internet Options dialog box.
11. In order for you settings to take effect, you must shut down Internet Explorer and restart it.
Administrative Passwords: When upgrading from software build 81 to version 3.3.x.x, the administrative
password is lost. The administrator must input the password again after the upgrade.
Share Level Security Passwords: In software build 81, share level security passwords were not case-
sensitive. In software version 3.3.x.x, share level security passwords are case-sensitive. For example,
JaneD561 and janed561 would not be recognized as the same password.
Administrative GUI Access: Access the administrative GUI pages directly through the HP NetStorage
6000 address (either IP or name) rather than attempting to access through an IIS server that is redirecting to
the HP NetStorage 6000. Occasionally this hangs the device and it is necessary to reboot to access it
again.
Renaming extended File Volumes: The HP NetStorage 6000 does not allow extended File Volumes
(volumes that have been extended across two partitions) to be renamed.
Context-sensitive help: The HP TopTools help button is not context-sensitive to the HP NetStorage 6000
page you are viewing. Press the ? button in the upper right corner of the page to view context-sensitive help.
IP address: If DHCP is enabled, but fails, the HP NetStorage 6000 may revert back to a previously
assigned static IP address. This may lead to some confusion as the NetStorage web interface indicates that
DHCP is enabled (which it actually still is), even though it failed and the IP address was not DHCP
generated.
Front panel Ready message: The front panel LCD displays Ready prior to the HP NetStorage 6000
actually being accessible. You should wait until the LCD displays the System Name and CPU Load before
trying to access files.
Backup - single file restore: When doing a single file restore the name of the file being restored is NOT
case sensitive. As an NFS client, when you restore a file that contains the same characters, you will get a
restore of all the files. For example, a file named GoodDoc, GOODDOC, or gooddoc will all be restored as a
single file restore operation.
Spanned tapes in backup: When a single file spans two tapes during a backup operation it is possible that
the ACL information for this file may be corrupted. The data integrity of the file is however, never in
jeopardy. To restore the ACL an administrator or root can take ownership of the file and set the appropriate
permissions.
NIC port order: The PCI bus is scanned from right to left (as viewed from the front of the HP NetStorage
6000). NIC cards would, therefore, be expected to be discovered in the same order. However, single port
NICs are always discovered before dual port NIC cards and may, therefore, cause confusion regarding the
mapping of physical ports to port numbers. In general, scanning from right to left (as viewed from the front of
the HP NetStorage 6000), the first single port NIC is Port 1. For dual port NICs, the bottom port is numbered
logically lower than the upper port.
Dual-port NIC card: Computer Associates Unicenter TNG Framework may have problems properly
detecting and classifying an HP NetStorage 6000 box that is using a dual-port NIC card. If this problem
occurs, one port is properly identified under Network_Storage > HP_Storage and an icon is displayed in the
Unicenter TNG 2-D Map. The other port is classified under Interface > IP_Interface and does not have an
icon associated with it. All traps associated with the HP NetStorage 6000 are sent to the Unicenter TNG
Event Console Log. If using a dual-port NIC card, it is recommended that the Unicenter TNG Event Console
Log is used to manage the HP NetStorage device rather than the Unicenter TNG 2-D map.
Multi-NIC connectivity: Connectivity issues may arise on a multi-NIC HP NetStorage 6000 if a client is
running Windows 95/98 or NT Service Pack 5 and trying to access the NetStorage 6000 by its IP address.
Possible workarounds include upgrading the client to NT Service Pack 6 or accessing the NetStorage 6000
by its system name instead of its IP address.
Host file management: The NetStorage web interface does not allow a host to be added to the local host
file if the host is already present in the host.nis file. A work around is to bypass the web interface and
manually add the host entry to the local host file.
File Security: NT Security Descriptors display the wrong owner information if the domain\administrator
takes ownership of the file. Instead of displaying the owner as domain\administrator,
XXXXX\administrator displays (where XXXXX is the HP NetStorage system name).
File Security: Domain\administrator that have no rights to a file can still change the permissions on a file
without first taking ownership of it.
File Security: If the system is a member of a Windows 2000 domain (configured in mixed mode), with trust
relationships to other domains, then taking ownership of files may not work as expected. Domain users on
NT 4.0 workstations will not be able to take ownership of files stored on the NetStorage 6000. On NT 4.0
workstations, only domain administrators will be able to take ownership of such files. On Windows 2000
workstations, this limitation does not exist, although the user may see an erroneous message box stating the
contrary.
User mapping strategy: An NT to UNIX user mapping strategy (no user mapping, user name mapping or
full name mapping) should be chosen prior to giving end users access to the HP NetStorage 6000. Based
on the mapping strategy selected, the system adds entries to the user map files (even if no user mapping is
selected). Changes to mapping after users have already attached or created files may result in users not
having expected ownership of previously generated files or expected mapping not taking place on newly
generated files.
Workstations with login restrictions: In cases where an administrator has established workstation login
restrictions (for example where a user is restricted to logging into one workstation and one workstation only)
they will be challenged for a password and will be unable to access the NetStorage 6000. The administrator
should remove login restrictions to prevent this problem.
Removing a user or group: Entries in the user map file are not automatically removed when a user is no
longer in the passwd.nis file. Entries in the map file must be manually deleted.
Entries in the group map file are not automatically removed when a group is no longer in the group.nis file.
Entries in the group map file must be manually deleted.
After Backup, file volumes disappear: After restoring files from a backup tape the browser may contain
stale or incorrect information about the file volumes. Selecting Storage > File Volumes shows that no file
volumes are configured. Either click the Refresh button on the browser for the correct file volume
information to appear, or close the browser window and open another one.
E-mail Notifications: The URL pointing to the failed device always uses the host name instead of the IP
address, even if the host name is not resolvable via DNS. In such cases, clicking on the URL causes
unpredictable behavior.
System log online help: The online help for the system log references specific notes for Redhat Linux 6.1.
This note should include Redhat Linux 6.x and 7.0.
Shared resources: There is a known issue with reusing a share point name after deleting a shared
directory from a client OS (as opposed to removing it from the NetStorage 6000 web management user
interface). The share name cannot be used again since the NetStorage 6000 retains this name and will
indicate that the name is still being used. The only way to remove the name is through the telnet interface.
For example, if a share point is created in the web management interface for directory \vol1\SharedDocs,
called SharedDocs, and this directory is then deleted from a Windows NT client (not using the web
management interface), the share name SharedDocs cannot be used again as a share point name.
Partition Size Limit: The HP NetStorage 6000 has a limit of 256GB (262144 MB) per partition.
File Volume Size Limit: You must select 262144MB or less when formatting partitions into file volumes. To
create a file volume that is greater than this, simply use the “Expand File Volume” feature to distribute space
across multiple partitions.
DLT Autoloader 818: This device has a maximum native capacity of 320GB, and a compressed capacity
between 480GB and 640GB, depending on compression efficiency. On an HP NetStorage 6000 that is fully
loaded with 73GB drives, it is possible that the stored data will exceed the storage capacity of the tape
device. In such situations, split the data into at least two sets, and back up each data set separately.
Drive Rebuild Time: When rebuilding drives, it may take a long time to initialize a logical drive (RAID set)
containing 73GB drives. The rebuild time is dramatically affected by how much the logical drive is being
used for file serving operations at the time of initialization. This also applies to logical drives that have failed
over to a hot spare, and to the rebuild of a replaced drive.
Reboots after Drive Changes: When drives are removed, added, or replaced while the system is powered
down, it is normal for the device to execute two boot sequences when it is powered on. This is required to
synchronize the RAID controller with the new drive configuration.
IBM Tivoli NetView – This management application is no longer supported.
General Browser Issues
Performance: After changing NIC parameters and clicking Apply, the browser may appear to hang while
the operation completes. The delay in the system responding is a function of the number of NIC ports and
changes requested.
Performance: Browsing the directory tree, and deleting directories from within the configuration interface
can take a long time, depending on the number of files and directories stored on the system. During such
operations, the web browser may appear to hang.
Security warnings: Denying additional privileges to Hewlett-Packard in a security warning window in
Netscape generates additional security warning windows. Granting privileges in one of the succeeding
windows does not actually grant the privileges needed. You must grant privileges on the first security
warning window.
Internet Explorer Issues
Error on exit: Some versions of Internet Explorer may generate the following application error on exit:
The instruction at "(some address)" referenced memory at "(some other address)." The memory could not be "(read or
written)."
This does not cause any problems managing the HP NetStorage 6000, but is a nuisance. Try upgrading to
the latest version of Internet Explorer to solve this.
Viewing multiple devices: You may not be able to view pages from two or more HP NetStorage 6000s at
the same time with some versions of Internet Explorer. Additionally, you may not be able to view pages from
two or more web-manageable devices that have similar user interfaces. Upgrading to the latest version of
Internet Explorer version may solve this.
Netscape Navigator Issues
Netscape Navigator ver. 6.0: The NetStorage 6000 web management user interface does not support
Netscape Navigator ver 6.0. Use a previous version of Netscape or Internet Explorer to view the
management GUI.
Java applets: The NetStorage 6000 interface is a web-based utility that makes extensive use of Java
applets. In some versions of Netscape, Java applets are known to fail to execute on occasion. If some
portion of the management interface fails to function, re-launch the browser to reload the applets.
Index search: If you are on a UNIX system and using Netscape as your browser, the search field in the
index of the online help may not display correctly. You can use the scroll bar to locate the entry you are
looking for.
Resizing browser window: On UNIX systems using Netscape, resizing the browser window may cause the
entire management interface to reload. When this happens, the browser may not advance past the Loading
HP NetStorage 6000... page. If this happens, press the browser's Reload button.
Event log scrolling: On UNIX systems using Netscape, the Status > Event Log page may not show a
scroll bar. Click in the event log area and use an arrow key; the scroll bar should then appear.
Browser loading: On UNIX systems using Netscape, the browser window may not advance past the
Loading HP NetStorage 6000... page when you press Reload. If this happens, press Reload again.
