We have one RAID5 with five disks and had another RAID0 with single disk in our R710. We take out that single disk and inserted into another server, imported foreign config - all okay. Then we inserted that disk back to original server and now not sure what to do. We don't see foreign config in Foreign View. Tried to restart server several times. We would like to have original configuration.

Just worry about importing foreign config without viewing it. Need your advice.
Solved! Go to Solution.
I suggest that you pull a controller log and then make sure the PERC firmware is at the latest. Update the firmware if an update is available. Make sure the disk is fully seated in the slot. If the drive is not fully inserted then it may be detected but not allow full communication. The controller log should have details about what is happening.

Updated to latest firmware, no luck. Tried to import, same thing.
Well, we did clear foreign configuration, created new virtual disk without initialization and all data preserved! Thanks.
