Hi,
We are using ESS vpath devices and running AIX 5.1 ML 7
There was a hardware issue with a LUN and partitions using it were marked stale. The ESS is now fixed, but we got 'media surface error on re-syncs. I moved everything off the disk and tried to create a new filesystem, but I still get the same error.
IBM hardware have told us that the disk needs reformatting - I think the problem may be a bad block list that hasn't been cleared. My guess for a reformatting would be the removal of the vpath from the VG, then rmdev of vpath and associated hdisks. Then a re-probe. I'm not sure about how I then might resolve the hdisk to vpath relationship.
Does anyone know if this will do the trick, or if there is a better solution ?
