Power Edge R710 RAID controller Battery Failure

Question

Hello,

I have a R710 with PERC H700 which suffered a power module failure and shutdown unexpectedly. I replaced the power module and when I boot up, I see a E1211 battery failure for the RAID controller and it is not detecting the virtual disk created as RAID1 using drives from Bay 0 and 1. Did I just loose all config info for the virtual disk? Can they be recovered?

Thanks,

Sarin

The images finally loaded for me here. You might look to see if 0 and 1 show up under the PD Mgmt section of the PERC tool. Ctrl + N should get you there. If they don't show up, you might reseat them.

Sarinj,

I wouldn't say that for sure yet, it may be a failed controller or maybe backplane. Would you confirm what you see under the Physical Disk page in the controller, is it showing the drives? Also, are you seeing a Foreign Configuration notification?

Lastly, if there is no backup and the data is critical you can also look at taking them to a data recovery company.

Let me know.

Hello and thank you for your reply. This is how it looks like. Am using Dell PowerEdge PERC H700 6Gb/s 512MB SAS RAID Controller R374M XXFVX in this box. I have 6 bays filled with the same type of 4 tb disks. Bay 0 and 1 were used for creating a mirrored (RAID 1) virtual disk. the remaining 4 disks are used to create the virtual disk 1.

Right now I can see only VD1. The other one is missing. Would replacing the battery on the RAID controller bring the data back? Also since the data is mirrored, can I take one disk out and access its data in a different box?

Thank you,

Sarin

Your images aren't loading for me, so I can't comment on questions relating to those, unfortunately.

That being said, I wouldn't expect a battery replacement to make any impact on virtual disk detection. To answer your other question about reading the data in another system, it should be possible, but it isn't a process that we recommend.

is there any chance I can send these images so you can view them?

Tha problem was with a caddy that was not properly set and now the system is back online. However, its now showing a foreign configuration present. If I import the foreign configuration, would it mess up the remaining virtual disk configuration?

I am going to order a new replacement battery for the controller. But if I import the foreign config that should get my system back to normal and won't remove the other virtual disks, right?

Yes, you are right!

Thank you very much for your suggestions. I was able to import the foreign config successfully and got the server booted up and back online. Much appreciated for your help. I am planning to get a battery replacement done immediately.

Hi, it looks like you'll most likely to need to replace batteries. However, do not force write back.
