Last updated on APRIL 17, 2023

Symptoms

• One node is showing a disk as missing and the other node of the HA shows the disk as path partially loaded.
• Checking the diskdiag shows that the disk is good.
• Trying to add the disk to the ODA using the ALTER DISKGROUP add DISK command fails.
• Running the oakcli stordiag e0_pd_## is failing to connect to the opposite node although we can run the command on each node one at a time.
• The disk does appear to be recognized on one node for many key queries.
• The disk can be seen physically and by the OS.
• The last major change for the system was a patching which happened months ago.

Changes

None identified: The problem with the disk was only detected while preparing for a new patching event.

In the past one a few disks had been replaced on the ODA configuration, but it was months ago.
Also, the last patching had taken place several months earlier.
