I thought I'd post a followup to this thread. I successfully fixed my
configuration. Everything appears to be sync'd. Just confirming
where I went wrong when I first tried to fix this, I had run 'cfgmgr'
while my primary node had the disk resources, so no pvid's were
imported from the command. After shutting down the cluster on both
sides and running cfgmgr after all the disks were rmdev'd, lspv
reported pvid's. Hopefully, my adventure and punishment is subsiding
now.

Key lesson with HACMP - Never automatically do what 'diag' tells you
to do (i.e. rmdev a scsi device) when troubleshooting scsi devices.

HTH someone else.
