I've got an HP ProLiant DL380 Gen7 with a Smart Array P812 which is connected to an MSA20 that houses 19 600GB drives.

After my VMs didn't boot up, I checked my array config and 2 drives failed:

=> ctrl slot=1 logicaldrive 1 show

            physicaldrive 1E:1:20 (port 1E:box 1:bay 20, SAS, 600 GB, OK)
         Drive Type: Data
         LD Acceleration Method: Controller Cache

So out of my 19 Drives (18 + 1 Spare) 2 suddenly failed.

My understanding of RAID 60 is, that 2 drives per parity group may fail without losing data.

Can I somehow force the array to get online to copy the files to other drives?

Thanks for help in advance, I know my gear is ancient.

EDIT: It's an MSA70, not MSA20!

    Power everything down. Power the MSA20 off. Let the drives spin down. Leave them off for a few minutes. Then power it all back on and closely monitor the system boot messages. – ewwhite Nov 21 '19 at 15:40

Most likely some drives in Parity Group 0 failed, and controller had started rebuild using the spare drive. During the rebuild another drive (or drives) failed, seen that a few times.

It's hard to say precisely what happened if you do not have some logs or monitoring data (iow - if you looked at controller status only after boot problems). You can look at ctrl slot=1 pd all show

Most likely you will see failed spare. Most likely you won't be able to bring your data back without backups.
