Follow these instructions to upgrade the Oracle FS Path Manager (FSPM) software without rebooting the host.
- Download the new version of FSPM.
- Log in as root.
- Take all Oracle FS System or Pillar Axiom LUNs out of use on the host.
Example: Vary off any volume groups using Oracle FS System or Pillar Axiom LUNs. The Oracle FS System Manager (GUI) shows path counts of 0 when these LUNs are out of use.
- Remove the configuration from AIX for all Oracle FS System or Pillar Axiom LUN disk devices.
These devices have the description
MPIO Oracle FS FC SCSI Disk Drive or
MPIO Oracle FS iSCSI Disk Drive.
Use the following command to remove the
Oracle FS System or Pillar Axiom
LUNs:
# rmdev —l hdiskx
Where
hdiskx is the name and number of the device.
Tip: If the command fails, it will most likely be because the device is still in use. Take the device out of use, and then repeat the command. The LUN Name on Host column in the Oracle FS System Manager (GUI) will be empty when the device configuration has been removed from the host.
Important! Do not proceed further until all Oracle FS System or Pillar Axiom LUNs have been taken out of use and their device configuration has been removed from the host.
- Install the FSPM software but do not reboot the host.
- Recreate the configuration for the LUNs, and bring the paths and LUNs online.
Use the following command to create and activate the new configuration:
# cfgmgr
It may be necessary to run cfgmgr more than once to bring all LUNs and paths online.
- Start the FSPM daemon to complete the task.
Run the following command to start the daemon:
# startsrc —s fspmd
Tip: After you start the daemon, the Host Information pages in the GUI could take a minute or two to display updates. The version of FSPM currently running on the host is shown in the Identity tab.
Note: You do not need to disconnect or connect paths during an upgrade.
