In my lab I’m using a Proliant DL380 G5 filled with disk as a storage server, running some VSA on top of the volume I created and formatted with a vmfs filesystem.
From here, let the fun begin! There are many commands you can run on the raid controller by running /opt/hp/hpacucli/bin/hpacucli, I’m going to show you some of them:
First, I identified the controller. Remember is in slot 3, this will be needed in the next commands.
As I said, my problem seemed to be related to the cache battery, so I went to check its status:
The status seems to be ok, but I went to enable anyway the cache, the command is:
1 | ctrl slot=3 modify dwc=enable forced |
Go to check it. As a last example, a fun stuff:
First, I identified the physical disks in the controller (pd), then I enabled the led on every single disk. This is the result
So you can see from the output above that there’s a 1.4Tb Logical Drive and 2 unassigned 300Gb SAS drives. I ran
=> ctrl slot=0 array A add drives=2I:1:7
which added disk 7 into the array. This process took just over 24 hours.
I then ran:
=> ctrl slot=0 array A add drives=2I:1:8
which added disk 8 into the array. This process also took just over 24 hours.
A further running of
=> ctrl slot=0 show config detail
showed that both drives were added to the array. However the space as reported in the HP System Manager was still 1.4Tb (same as before).
The last step was to expand the array:
=> ctrl slot=0 ld 1 modify size=max
Once this had completed (it took a couple of seconds), all that needed to happen was a reboot for Windows to recognise the new space. I then connected to the Hyper-V host via Computer Management and extended the available space with Disk Management.
