Normal fiberchannel devices are named
cXtWWPNdLUN
Example:
/dev/dsk/c5t21000080E511F169d0
WWPN in this case is 21:00:00:80:E5:11:F1:69. It appears as "target" in the standard Solaris SCSI notation.
The problem: If you got multiple paths (to multiple WWPNs) to your devices, your volumes will appears as many identical volumes - one for each path:
How to correct this?
Tell scsi_vhci to accept this "LSI ProFibre"-Device as multipath device:
Set a suitable region size to use logical-block round-robin:
Result:
Wonderful.

Hi,
5*. Really Wonderful article. Helped me a lot. How do you manage the SAN? I have a ProFibre 4000R connected to a solaris 8 sparc box, running veritas cluster and veritas volumemanager with LSIProFibreASL package installed. All disks are configured in several raid 5 pools. The mlxcfg and mlxutil utilities are running fine:
root@sol8# /opt/mlxcfg scan
e-Array Director CLI v4.00.53 pre-release -- SIT Version: v4.0.71
Controller: 0
Name : MYLEX DACFFx2
Path : External Fibre
SCAN command succeeded
I cant find the management tools to use in a solaris 10 sparc box (without veritas cluster or vxVM) anywhere. Can someone you me?
Thanx
