PowerScale OneFS Upgrade Planning and Process Guide

Check hardware health - CLI

1. To return information about cluster health and check for jobs or devices that report a status of ATTENTION, SMARTFAIL, or DOWN.

   isi status -v

2. To check for drives that do not report a status of HEALTHY, L3, or JOURNAL.

   isi_for_array -s 'isi devices drive list | egrep -v "HEALTHY|L3|JOURNAL"'

3. To check the mirror status of the boot drives on each node.

   isi_for_array -s 'gmirror status'

   NOTE:If a drive is degraded, do not continue with the upgrade until the issue is resolved.
4. If the cluster has an InfiniBand network, confirm whether a node has been assigned the OpenSM (subnet manager) main role.

   isi_for_array -s 'ps -auwwwx | grep opensm' | grep master

   Confirm that the output displays only one node in the cluster as the main (opensm). The output should be similar to the following:

   node-2: root   1610   0.0   2.3   436292   384672   ??   Ss   20May15   97:31.63   
   opensm: 0x00151b00007a671b main (opensm)
