Hi community! Here’s a case that the path status cannot be updated from failed to enabled automatically after the optical fiber is reinserted.

Symptoms

After an optical fiber is removed, the status of the path changes to Failed. However, after the optical fiber is reinserted, the path status is still Failed instead of being updated to Enabled.

Fault Diagnosis

This is caused by the path status check mechanism of AIXMPIO. In this mechanism, only when the disk is in open state, the path status can be updated from Failed to Enabled after the optical fiber is reinserted.

Solution

Solution 1:

  Create and activate VGs on the disk, and then the disk is in open state; therefore, the path status can be automatically updated.

Solution 2:

  Run the chpath command to set the path status to Enabled. The following is an example of setting the path status of hdisk2 to Enabled.

bash-3.2# # chpath -s enable -l hdisk2

paths Changed

bash-3.2#
