The IAD service should be running, as shown in the previous sample output. If it is not, contact HP
Support.
Installing a minor kernel update on Linux clients
The X9000 client software is upgraded automatically when you install a compatible Linux minor
kernel update.
If you are planning to install a minor kernel update, first run the following command to verify that
the update is compatible with the X9000 client software:
/usr/local/ibrix/bin/verify_client_update <kernel_update_version>
The following example is for a RHEL 4.8 client with kernel version 2.6.9-89.ELsmp:
# /usr/local/ibrix/bin/verify_client_update 2.6.9-89.35.1.ELsmp
nl
Kernel update 2.6.9-89.35.1.ELsmp is compatible.
If the minor kernel update is compatible, install the update with the vendor RPM and reboot the
system. The X9000 client software is then automatically updated with the new kernel, and X9000
client services start automatically. Use the ibrix_version -l -C command to verify the kernel
version on the client.
NOTE: To use the verify_client command, the X9000 client software must be installed.
Troubleshooting upgrade issues
If the upgrade does not complete successfully, check the following items. For additional assistance,
contact HP Support.
Automatic upgrade
Check the following:
• If the initial execution of /usr/local/ibrix/setup/upgrade fails, check
/usr/local/ibrix/setup/upgrade.log for errors. It is imperative that all servers are
up and running the X9000 Software before you execute the upgrade script.
• If the install of the new OS fails, power cycle the node. Try rebooting. If the install does not
begin after the reboot, power cycle the machine and select the upgrade line from the grub
boot menu.
• After the upgrade, check /usr/local/ibrix/setup/logs/postupgrade.log for errors
or warnings.
• If configuration restore fails on any node, look at
/usr/local/ibrix/autocfg/logs/appliance.log on that node to determine which
feature restore failed. Look at the specific feature log file under /usr/local/ibrix/setup/
logs/ for more detailed information.
To retry the copy of configuration, use the following command:
/usr/local/ibrix/autocfg/bin/ibrixapp upgrade –f –s
• If the install of the new image succeeds, but the configuration restore fails and you need to
revert the server to the previous install, run the following command and then reboot the machine.
This step causes the server to boot from the old version (the alternate partition).
/usr/local/ibrix/setup/upgrade/boot_info –r
• If the public network interface is down and inaccessible for any node, power cycle that node.
