Hi,

What type of san do you have?

I think it is the device file of the controller

Hi Ehrler,

Whether these disks are comming from a EMC Clarion SAN Storage..

1.fcp 2 0/0/12/0/0.1 fcp CLAIMED INTERFACE FCP Domain
ext_bus 20 0/0/12/0/0.1.0.0.0 fcparray CLAIMED INTERFACE FCP Array

This device is for the Storage Array.

2.Interface target 11 0/0/12/0/0/0/0 tgt CLAIMED DEVICE
disk 9 0/0/12/0/0/0/0.0 sdisk CLAIMED DEVICE DGC CX600WDR5
/dev/dsk/c20t0d0 /dev/rdsk/c20t0d0

This device if for one of the Disks from the mentioned Array

3.ext_bus inteface 11 0/0/12/0/0/1/0.255.0 fcpdev CLAIMED INTERFACE FCP Device
ctl 11 0/0/12/0/0.1.0.255.0.0.0 sctl CLAIMED DEVICE DGC CX600
/dev/rscsi/c11t0d0

This one is for controller in the Array

You can identify this with the driver whats being used for this device

Whther your Queries got cleared ?
