MSA 20 and Failed 2 TB disk drive - 507774-B21

[patv]

I have an old StorageWorks MSA 20 with a failed 2 TB 7.2K SATA disk drive, part # 507774-B21 in a RAID 6 plus hot spare configuration. The array and logical drives are now using the spare. Two questions;

1. The drive is described as non-hot pluggable. Do I need to  power down the MSA 20 to repklace the drive?

2. Can I replace the drive with part number 508040-001 which is a 2 TB 7.2K SATA but hot-pluggable?

Thanks.

The MSA20 is a hot-plug disk enclosure, so any drive that is installed is hot-pluggable.  It sounds like someone took a bare drive meant for an internal system such as a ML or desktop and attached the hot plug bracket to it.

You will be fine in hot-plugging the disk and swapping out the one you mention.  If you look up the part numbers here you will see that the two HP part numbers share the same drive model:
