Re: DL380 g3 hard disk replace

Is it a 'hot-plug' drive in a RAID?
(Assuming that you're talking about a failed drive)

is there any command to check if server controller support hot-plug or not ?

Re: DL380 g3 hard disk replace

It's quite easy to see...

If the HDD is 'out in the open' in front, with lockable handles to pull it out, then it's hot-pluggable.
If you need to remove a cover and disconnect a cable, it's not hot-pluggable.

Thanks for your support.

Re: DL380 g3 hard disk replace

Why do you want to replace the hd?
has it failed or do you want it to replace it with a bigger or faster one?
Make sure what you are doing. Since the server is clearly important you might not want to risk breaking an array set.

HD is failed so i need to replace it.
do you think replace HD without turn off server could cause any problem?

Re: DL380 g3 hard disk replace

If the disk is in a RAID 1 or 5 array, there shouldn't be any problems.
The controller will automatically detect the replacement and start rebuilding it.

RAID 0, though, means the array is shot anyway, and that someone screwed up royally when setting up the server.

A disk NOT in an array may or may not require a restart of the server in order to detect it. (Depends on the OS. mostly)
