[cisco-voip] Can you use the same instructions

[Lelio Fulgenzi]

we've been told there's a fundamental difference between hot pluggable and hot swappable. The servers support hot pluggable which we're told means you can plug in a drive at any time....but not unplug it. We've got this from HP support, TAC, and many Cisco employees.

Although the  HP servers support the hot plug in a repetative drive mirroring regiment - the IBM servers (7855) do not. I believe their MTBF count for the insertions of those drive systems is much much lower than you would expect.

  The RAID controllers are hot-plug ... you can pull a drive while the machine
  is up and replace it with another one and it will start mirroring from the
  live, working drive.

  We have always done this using the "top" drive on HP servers (drive 1 versus
  drive 0) so I am not sure if this is the only drive that can be hot swapped
  or if you can do so with either drive.  I think it used to be only this one,
  but maybe the RAID controllers allow either way now.

  I believe the drive replacement activity is hardware/RAID controller
  based rather than application based. Our drive replacement activities
  are the same on our HP servers (Callmanager) as they are on our IBM
  servers (Unity). 

  * shut down server
  * unplug drive
  * start up server
  * press the appropriate key to 'fail' the drive, but not change
  the configuration (HP=F2, IBM=F5)
  * after server has booted up, insert spare drive
  * confirm drive has been mirrored using appropriate utility

  Can I use the same instructions to remove a drive and replace on my
  Unity 7835 as I do on my CM 7835?

  TIA
