For customers with MegaRAID BIOS and LSI RAID cards on SSB appliances that are replacing a failed disk.
The LSI card does not automatically rebuild the mirror onto the newly replaced drive. The drive is put into the UNCONFIGURED BAD state and requires manual intervention to initiate a rebuild. With the LSI there is no way to initiate an array rebuild (or do any array maintenance for that matter) so a reboot into the LSI BIOS is necessary.
Even though the drive has been physically replaced, the BIOS shows that there is a “PD Missing” on backplane X, slot Y.
By switching to the “physical view” and selecting the drive that’s shown as “Unconfigured Bad”, the drive can be changed to “unconfigured good” by marking the radio button and clicking Go.
Now that the drive is in a “good” state, it can be added into the array by marking the radio button beside Replace Missing PD and hitting Go.
After that, choose to Rebuild Drive.
