Before I start let me just say I am somewhat of a 3PAR noob. We have a 7400 running 3.1.3 MU1. We have a very basic configuration and I know I am not using the 3PAR to its full potential.
Summary – I have 5TB of RAW space that I want to use to expand two of my virtual volumes by 1 TB each. Based on my reading this should be as simple as a “growvv <vv name> 1t” right?
Details -
My configuration is very simple.
7400 (2) controller config with 8 cages and 80 identical disks.
3 CPG’s to control Raid lvl and some other small stuff like protection level.
CPG_RAID_1
CPG_RAID_5
CPG_RAID_6
1 virtual volume per CPG
VV_RAID_1
VV_RAID_5
VV_RAID_6
All three VV’s are part of a virtual volume set that is exported to a host set that contains all 16 ESXi hosts. There is no boot from SAN and all 3 VV’s are configured as separate vSphere datastores that all ESXi hosts have access to.
So I have 5TB of RAW free space (5465.000 Gib), to add 1 TB of storage to my Raid 1 virtual volume I would issue the following command.
growvv VV_RAID_1 1t
This would increase the capacity of this virtual volume by 1TB and reduce my free space by roughly 2TB because it is raid 1 right?
Note: my VV_RAID_1 is currently 5TB, I am not employing any copy space so my VV_RAID_1 summary right now shows:
User space: 5,120.000GiB
Copy Space: 0.000GiB
Admin Space 0.000 GiB
I was just wondering if there was anything else I was missing that would be service interrupting or any known O rings?
