were previously online are offline after running clxrun; then, remove the XP Cluster Extension

Removing XP Cluster Extension Software for AIX

Before removing XP Cluster Extension, consider the following cautions:

CAUTION:

Before you can remove XP Cluster Extension from the system, you must first stop the resource group

or switch the resource group to another system, and then remove the pre-event entry for XP Cluster

Extension from the get_disk_vg_fs and release_vg_fs events.

CAUTION:

Deleting the XP Cluster Extension integration from an online resource group or cluster does not remove

the resource_name.online file. It also does not remove the device group from the list of monitored

device groups if the pair/resync monitor is used to monitor the XP Continuous Access link. Therefore,

the device group must be deleted from the list of monitored device groups manually using the

clxchkmon command after deleting the XP Cluster Extension resource. See “Stopping the pair/resync

monitor” in the “XP Cluster Extension and CLI” chapter of the

HP StorageWorks XP Cluster Extension

Software Administrator Guide

for instructions.

CAUTION:

Failure to delete the monitored device group from the list of monitored device groups can cause data

corruption if the ResyncMonitorAutoRecover attribute is set to YES.

The following command removes XP Cluster Extension for AIX from the system:

#smitty deinstall
