I have a failed disk in my md1200. It was part of a redundant virtual disk (raid5) with a hotspare. The virtual disk has been rebuilt with the hotspare and is showing status green. The failed disk is blinking amber in the md1200. There are no options to take the disk offline in OpenManage 7.4, just blink/unblink the drive. I am expecting a replacement disk tomorrow. The manual gives me two steps to replacing a disk in the above scenario, the first is:
1. Remove the failed disk. (!)
Can I simply press the release button and pull the drive out whilst the leds are blinking amber? Or do I need to do something else? The cli utility details a command to prepare a drive for removal, but gives no further explanation . . .
You can just pull the failed drive out of the MD1200 & then once your replacement drive has arrived you can insert it into the empty slot since your hotspare drive has finished the rebuild successfully. The drive should have powered down once the MD1200 marked it as failed but I have seen this happen a few times & pulling the drive should not harm your raid 5 virtual disk.
Please let us know if you have any other questions.
And just for completeness here is the output of omreport for the failed disk:
Thanks

Thanks for the answer, very reassuring. The disk has arrived, I've swapped out the failed one, and currently OpenManage is showing the new disk as 'replacing', which I presume means it is being populated with the data on the hot spare, which will revert back to being a hot spare one complete.
Incidentally the time between the first SMART warning of impending disk failure and actual disk failure was about 30 minutes - which is quite short, especially at midnight!!

Hello davetoo2,
