Changing AIX LUN paths
Hello,

Looking for some guidance to changing how an AIX 6.1 server sees its luns. Presently they're connected via 1GB iscsi but I want to change it to 4GB fiber channel. Anyone done this before and if so is it an easy step?

I'm thinking this can be done in this order:
  1. unmount the filesystems
  2. varyoffvg vg
  3. make the changes on the storage system (EMC)
  4. cfgmgr
  5. varyonvg vg
  6. mount the filesystems

I've never done this before so I'm hoping its that simple but IBM is never that simple.

Any help is much appreciated.

       iscsi - iSCSI software initiator driver

       The iscsi driver is a software initiator that transports SCSI commands over TCP/IP as described in RFC 3720.  The initiator is administered
       through iscsiadm(1M). The iscsi initiator acts as a host adapter driver that attaches the appropriate target driver (for example sd(7D) for
       disks or st(7D) for tapes) for devices it discovers.  See the System Administration Guide for more information.
