Assign Storage to IVM From IQstor

IVM storage has to be MPIO or has to be part of a volume group, as in, it need a PVID, a Physical Volume Identifier. If those requirements are not met you cannot assign storage to a LPAR in IVM. Since we also boot from the IQstor it's not possible to install the MPIO software from IQstor, booting is not supported and will fail (we tried, it won't work). So MPIO is not an option, so the only solution is to create a PVID for the hdisks.

Create PVID For HDisk

First, go into normal command mode:

$ oem_setup_env

List current physical volumes:

# lspv
hdisk0          000a447aa92d7d0a                    rootvg          active
hdisk1          none                                None
hdisk2          000a447ab395ffe2                    None
hdisk3          none                                None

Discover new physical volumes:

# cfgmgr
# lspv
hdisk0          000a447aa92d7d0a                    rootvg          active
hdisk1          none                                None
hdisk2          000a447ab395ffe2                    None
hdisk3          none                                None
hdisk4          none                                None
hdisk5          none                                None

Create a volume group (this will create a PVID for the disk) and then remove the volume group:

# mkvg -y testvg hdisk4
0516-1254 mkvg: Changing the PVID in the ODM.
testvg
# lspv
hdisk0          000a447aa92d7d0a                    rootvg          active
hdisk1          none                                None
hdisk2          000a447ab395ffe2                    None
hdisk3          none                                None
hdisk4          000a447ac234793d                    testvg          active
hdisk5          none                                None
# reducevg testvg hdisk4
ldeletepv: Volume Group deleted since it contains no physical volumes.

Now the disk has a PVID:

# lspv
hdisk0          000a447aa92d7d0a                    rootvg          active
hdisk1          none                                None
hdisk2          000a447ab395ffe2                    None
hdisk3          none                                None
hdisk4          000a447ac234793d                    None
hdisk5          none                                None
