I have a customer looking to implement Power10,  VIOS, AIX, FlashSystem 5300 using iSCSI.

Personally I've only ever used PowerVC with SAN based storage connectivity.

I just want to confirm that PowerVC 2.1.1.2 will support iSCSI storage connectivity to AIX LPARs? I think it should as the iSCSI network would just be another network definition in PowerVC and the LPARs would have connectivity to the iSCSI network as well as the user and management networks.

Any thoughts or comments appreciated.

I've had an AIX with hanged I/O on software iSCSI.  Support wouldn't address it stating that the only supported SW target was the AIX target.

Make sure that the full combination is on SSIC.  If it's not, forget it.

Make sure you're using 25Gbe, or 100Gbe.

Personally I wouldn't touch it unless I already had a well-tested environment.

José,

I'm with you on this but it's not my decision.

It will be connecting to FS5300 so that should be fine.

I just need to know if PowerVC with FlahSystem and iSCSI.

There is also iSCSI support from VIOS 3.1.0 or later: https://www.ibm.com/docs/en/power10/9105-41B?topic=overview-iscsi-disk-support-vios.

Hi Glen,

ISCSI is not supported in PowerVC currently. We do have an Idea here for iSCSI support https://ibm-power-systems.ideas.ibm.com/ideas/PVC-I-359. Please do vote for this to help us consider the idea in our future release.

Thank you,
