[cisco-voip] replacing disks under new linux O/S

[Ryan Ratliff]

You'll see it in the system event log when the array detects the  
failed disk and when it begins to rebuild the array.

If you are in front of the server the rebuild is finished when the  
drive leds stop blinking.
Other than whatever ILO may give you the only way to get into the ACU  
is via the BIOS.

I wasn’t able to capture a “show hardware” while rebuilding, I might  
have time to test more later this week.

I did a "show hardware" at the CLI and it gives disk stats. I'm  
hoping when I remove and insert the disk it will say rebuilding and  
so much percent.

Step 5, how do you pull up the HP/Compaq RAID Array Utility under  
Platform CLI? I have no idea but would also like to know.



This is a good example where the Appliance model is tougher than  
Windows.  In Windows you could pull up GUI, or watch Event Viewer to  
confirm raid rebuild status. Here they have to map a CLI/WebInterface  
into the HP ACU-CLI.



HP Array Configuration Utility CLI for Linux

This needs a re-write for Platform OS!

I've got a bad disk I need to replace in a Unity Connection 7  
installation. I haven't replaced a disk on a linux based appliance  
yet and I'm just wondering what the procedure is and how I monitor  
the RAID rebuild.

In the olden days, we use to:

shut down the server
remove the disk
turn up the server (press F2, F1 to keep the RAID config in broken mode)
insert disk
monitor using HP/Compaq utility
I suspect it's going to be something close to this, since it's still  
an HP, I'm guessing the F2, F1 sequence still exists, but I'm  
wondering what the monitoring software is going to be.
