We are not using iSCSI so I can't help that much, sorry - found those two articles on how to implement iSCSI:
SVC Information Center
This one on an example using CISCO hardware and a DS4000. As far as I could understand from other sites, the step where you have to define iSCSI targets in /etc/iscsi/targets and the chdevs etc. will be the same for other models of hardware:
Implement iSCSI on AIX
And one more:
Help -
If you get it working, leave a note here what did the trick, ty.
Not sure how good your german is - here is one more describing what to do:
Stor IT Back - herstellerunabhängige Beratung
Some translation of it:
- Since AIX 5.2 iSCSI is implemented to the OS.
- Need a working TCP/IP connection to the storage.
- Is a ping to the iSCSI target successful, you can the software initiator(?) be installed.
- With "smitty -> chgiscsisw" the iSCSI-initiator will be created.
- Further configuration has to be done in /etc/iscsi/targets.
Here an example performance tuning for iSCSI he describes in his article:
Quote:
ifconfig en3 down
ifconfig en3 detach
chdev -a ent3 -a jumbo_frames=yes
chdev -l en3 -a tcp_recvspace=262144
chdev -l en3 -a tcp_sendspace=262144
chdev -l en3 -a rfc1323=1
ifconfig en3 up
At the end he points at
Implement iSCSI on AIX too.

Previous forum threads have noted that AIX cannot use iSCSI disks because it fails when trying to add them to a volume group using mkvg. The failure is caused by AIX's use of the SCSI "WRITE AND VERIFY"(0x2e) command which some iSCSI targets do not support.
