How to find out the HP P2000 SAN storage usage

hpstorage-area-network

I have a HP P2000 SAN using for multiple purposes. I need to see the entire SAN storage usage, like free space, used space, raw space…

So far all I can get is the raw space and volume size from web console, there is no option for used space and free space for each volume or for entire SAN storage.

I could not find any command for showing such information.

Anyone knows anything about it?

To show information about disks:

show disks
[disks]|[free]|[all]|[vdisk vdisk]
[perf]

To show information about all disk slots:

show disks encl

To shop information for all or specified vdisks and see used/free capacity execute command

show vdisks 
[vdisks]
[perf]

How to find the usable storage space

You'll need to look at the properties of each RAID group to see how much space has been used on each RAID Group.

You can also get this info with the naviseccli from the command line.

NaviSecCli -h {ServerName} getrg

Differences between HP and EMC SAN

If this P2000 is anything like my old MSA4400, then vDisks are volumes that are assigned to servers as LUNs, but under the covers, what is happening on the HP has little in common with a Clariion.

The way I remember it, the HP has a bunch of disks that it sets up in fixed groups (with RAID, I think), and then vDisks are created that live on these disks with their own virtual raid. So you could have one vDisk with virtually raid 10, meaning each block or chunk that comprised the vDisk would be saved twice, and another one with virtually raid 5, meaning that the chunks would get saved once, but would have distributed parity.

I'm a little hazy on the details about the actual disks, whether there was raid under all these vDisks or just a JBOD. I do remember that we had global spares, because we had several dozen disks of about 100 fail over the course of three weeks, and the system was able to take the hits until more than 9 were rebuilding at the same time.

Maybe someone with more recent and specific P2000 experience can chime in here and help, but this is what I remember.
