It's giving me slightly conflicting results:
# /opt/MegaRAID/MegaCli/MegaCli -CfgForeign -Scan -a0
There is no foreign configuration on controller 0.
# /opt/MegaRAID/MegaCli/MegaCli -pdInfo -PhysDrv[8:1] -a0

This Drive Is Foreign.
I have just done a full clear of the drive history:
# /opt/MegaRAID/MegaCli/MegaCli -pdClear -start -PhysDrv[8:1] -a0
And it does appear to have cleared the drive - OMSA and MegaCli gave me
a progress bar, but its still showing as Foreign in OMSA and through
MegaCli.
Can anyone explain the mismatch between the controller state and the
disk state? It would certainly appear to be the disk I need to reset,
not the controller.
Mark.
