Hello,   Whether a drive is hotswappable or not is determined by whether you have a backplane or not. I don't believe the R610 offered a cabled drive configuration and all disks were connected through a backplane. As for identifying the disk, the failed disk should have either an amber LED, or an alternating green and amber LED pattern. If the disk has fully failed, then it is offline and is no longer an active array member and can be safely removed. If the disk is in a predicted fail state, then the drive would remain an active array member. Without OMSA, you won't have a way to offline the disk, so I would recommend shutting the server off for replacement in this case, due to environmental limitations. I know some people will remove a predicted fail drive without offlining and in many cases were fine, but this can create problems and is something I would actively recommend against, especially in a software RAID.
Hello, I have a failing hard disk on one of my servers, but it's in software RAID.  I don't have OMSA installed.  Are the SAS drives hot swappable for Linux?  If so, what's the best way to identify the failing drive by device so I pull the right drive to replace?
