When a drive enclosure (JBOD) is powered off abruptly as in the case of a power outage, the drives may not come up before the sensor head is powered up. The drives are seen as missing and then once they are powered on and ready are seen as foreign to the sensor. This may also happen when a single drive is replaced.
The resolution is simple once you determine the adapter number from lsi-show. The adapter number is either a0, a1, a2, or a3. It is found by running
lsi-show and looking under the Id in the "Controller Information" section. You will need to run
lsi-show to find the failed JBOD and then
megacli -cfgforeign -import -a1. Change the 1 to the Adapter number in your case.
For example, this is for Controller for Adapter a1:
Controller Information Id Serial No Firmware Encl LD PD Product Name a1 38T012N 3.130.05-2086 2 2 24 PERC H810 Adapter
Look for the Physical Drive Information that contains the "Unconfigured(good), Spun Up" drive. For example,
Physical Drive Information Id E:S Status FC Size Inquiry 9 12:0 Unconfigured(good), Spun Up Foreign 1.819 TB SEAGATE ST2000NM0023 GS0AZ1X0NUAD 8 12:1 Unconfigured(good), Spun Up Foreign 1.819 TB SEAGATE ST2000NM0023 GS0AZ1X0LNYK
Look a few lines above these to the first occurrence of "Controller Information" and find the Controller Id. If it says "a1" then it is Adapter 1.
Then run: megacli -cfgforeign -import -a1 If it works properly, run lsi-show and you should see:
Physical Drive Information Id E:S Status FC Size Inquiry 9 12:0 Online, Spun Up Foreign 1.819 TB SEAGATE ST2000NM0023 GS0AZ1X0NUAD 8 12:1 Online, Spun Up Foreign 1.819 TB SEAGATE ST2000NM0023 GS0AZ1X0LNYK
If there were multiple drives, you will need to run "reboot" to restart Security Analytics with the corrected Capture filesystem.
If you get an error that importing the configuration will create an inconsistent state in the RAID, please call Blue Coat technical support for further assistance.
