Event Timeline

contacted dell regarding failed drive will update with response

Thanks @Jclark-ctr , can you have the drive replaced this week? Also, you might need to coordinate with @jcrespo via IRC to get a couple other things completed to get backup1001 up and running. Thanks, Willy

Just to be clear, there may be new stuff coming (RAID setup), but it is not set on stone yet both on eqiad and codfw dcs. I will create one or two tickets when I have the specific configuration ready for you. I should have a request ready by tomorrow.

@Jclark-ctr @jcrespo SR# 997901435 . DPS# 717467224, and it is setup to arrive during normal business hours on Wednesday. Disk will be replaced Wednesday

@jcrespo Drive arrived early Replaced failed drive

Now instead of a failed disk, I can only see 23/24 disks, one disk of the second enclosure is gone. See:

root@backup1001:~$ sudo megacli -PDList -aALL | grep 'Device Id'
Device Id: 23

disks3.png (235×1 px, 17 KB)

I believe it to be 0:1:0, or the first disk of the second enclosure, the same previously reported as failed (but present). I would suggest to check the connection, otherwise this could be actual enclosure or raid adapter issues.

@jcrespo all Disk show connection light can you please reverify

I can see now 24, thanks!
