IBM AIX - Mirror Inconsistency Issue with a Logical Volume
Update on mazor Issue Scenario: There had been a mirror inconsistency issue with a logical volume. The issue was that there was a logical volume that had mirror copies, but one LP had 3 copies as against 2. Problem Identification: [servotsm01:root:/home/sysadmin:] lsvg -l Serverstgpvg Serverstgpvg: LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINT 0516-1147 : Warning - logical volume Serverstgplv may be partially mirrored. Serverstgplv jfs2 4017 8035 30 open/syncd /tsm/yar1/stg loglv01 jfs2log 1 2 2 open/syncd N/A The logical Volume Serverstgplv has 4017 LPs mapped to 8035 PP (which ideally should have been 8034 [4017*2]). The LV has 1 extra PP to it which implies, 1 LP has an additional copy (the 3rd copy) hence the giving the warning "logical volume Serverstgplv may be partially mirrored". Problem Diagnosis / approach: Step 1. Identify which LP has the 3rd copy. [servotsm01...
