[cisco-voip] Break Mirror on HP MCS

[Jason Aarons (US)]

You can't pull a SATA drive in a MCS-7825 hot, but I've pulled many SCSI
drives from DL-380s hot. The Event Viewer logs do a great job of showing
what's happening with the SCSI controller and the raid re-builds.  A
36GB drive takes almost exactly 45 minutes to re-build, it's all done in
Compaq hardware versus software.  Sure if you could power it off that
would be recommend, but I've seen a few sites with single MCS-7835 and
had to break the raid mirror couple days before a upgrade and powering
down wasn't a option.

 

Would you pull a 6724 or NAM or IDS module in/out of a 6509 hot?  Some
would say sure, others have lost switches on "hot-swappable" parts!

 

I know the IBM x440s we had you could replace CPUs and RAM hot in
production, only thing you couldn't swap hot was the motherboard!
24x7x365 non-stop computing!

I always shut down the Server.... Pull the drive.... Power up the
server.... Then put in the new drive.

 

I have never pulled a drive in use.  Probably not the best option.

I've ordered some spare HDs and wanted to use them to keep an extra
backup.  I'm used to working with Dell servers and had a bad experience
pulling a hot-swap drive live.  Their RAID controller allows you to
power down a drive to remove it.  I couldn't find a similar feature on
the HP interface.  Is this necessary or is it safe just to pull the
drive live.  Any help would be appreciated.
