Hello!
I am needing to provide a DS5020 LUN to an LPAR my Power 740.
There are some procedures to do this process.
Anyone have the correct sequence for this procedure.
I have some knowledge but still have some doubts.

If you're on a bare-metal AIX system, or an AIX system using NPIV:

1. Make a list of all FC adapters that are attached to this AIX system, and their WWNs.

2. In your SAN environment, make sure SAN zoning is done properly so that the AIX system can see the DS5020 and vice versa.

3. On the DS5020 create a LUN, assign it to the right WWN or WWN group for your AIX system.

4. On AIX: cfgmgr

If you're on an AIX system that sits behind a Virtual I/O server that does vSCSI, then the above steps 1-3 should be done, but use the VIO server instead of the AIX machine. Then:

4. On the VIOS: cfgdev

5. Use the HMC to figure out how which VIOS vSCSI server adapter is connected to your vSCSI client adapter in the AIX partition. Use the VIOS lsmap command to figure out the device name for the vSCSI server adapter.

6. On the VIOS: mkvdev -vdev <LUN name, such as hdisk19) -vadapter <vSCSI server adapter name, such as vhost12)

7. On AIX: cfgmgr
