HP array Raid 5 nightmare
Posted on 2010-08-19
On my MSA30, raid 5 configuration, I have 2 drive failures. Data is still accessible, but how can I resolve this issue. I have no redundancy now.My online spare did not initialize for some reason. See my correspondence from HP below.
Here we have the Level 2 action plan:
Unfortunately this is a raid 5 lun with at least 2 drives with problems,
disk 8:3 is on the status "replacement"
disk 8:1 has some errors as well
It is important to clarify that the lun may need to be recreated and data restored from backup as chances are to get the following options with no success:
1: Try to reseat drive 8:1, unseat, wait 2 minutes, put it back in, if the system recognize it without the errors it may start to rebuild
2. Reseat drive 8:3, but unseat the drive, wait at least 2 minutes and put it back
3. Unseat drvie 8:3 and wait until it is reported as missing or failed, in order to try force an spare drive to take over
4. Replace drive 8:3 with a new one (keep the original drive handy if needed )
I wil not recommend to risk the rest of the volumes on this enclosuse
if any of this does not solve the issue best recommendation is to recreate that lun
2 drives are going to be sent onsite anyway to be replace drives 8:1 and 8:3, drive 8:8 is not to be replaced as for now, if any of this steps make the rebuild process to start both drives need replacement .
