VIOS Shared Storage Pools - Reusing Disks
I am using the VIOS Shared Storage Pools more these days and it reduces my system admin time and I really like the Thin Provisioning feature as I have limited SAN disks. Any way, I dusted off an machine that I did my initial investigation on and decided to rebuilt the cluster (of one VIOS) now that I know what I am doing :-) The command : cluster -create -clustername galaxy -repopvs hdisk2 -spname atlantic -sppvs hdisk3 hdisk4 hdisk5 -hostname diamondvios1 fails with "PV IS IN USE hdisk4". PV meaning Physical Volume. Yes,... [More]

Shared Storage Pools (SSP3) and Disaster Recovery in 30 seconds
Shared Storage Pools - just got even more interesting ! SSP Clusters with disks pools and super fast disk allocation VIOS Shared Storage Pools (phase 3) allows 16 VIOS on different machines to operate as a VIOS cluster with a set of SAN LUNs in the pool - think in terms of a number of TBs of disk space in the pool. The VIOS systems administrator can then allocate disk space to a new or existing Virtual Machine (LPAR) in around a second which can be thin or thick provisioning regardless of the underlying disks. This drastically reduces the... [More]

Shared Storage Pools 2 - Up and Running + some New Information
At last I have got round to rebuilding my Shared Storage Pool cluster of machines. We have the four VIOS limit. So I was thinking: For machines with Dual Virtual I/O Servers - the options are limited so I would pair up machines for mutual Live Partition Mobility. For machines with single VIOSs - I would create a cluster of four machines for some extra flexibility and LPM across any of the machines. The "cluster -create" command to make the first node of the cluster too about 3 minutes and the "cluster -addnode" command... [More]
