Verifying Dual Path

How do i see the DUAL Path to my SAN on AS3? we do not use any multipathing s/w. Given that the case, how would i see the dual path to SAN. No LVM either..we just use fdisk.

Thanks

Brian

If you don't use multipath software or multipath capable driver, you will see at least two disks devices (sda, sdb) for the same lun.

Use inq (inq.linux) It will give you the storage info including the serial nos., etc,

If you have the powerpath s/w ; you can use powermt

Shalom Brian,

fdisk -l will show dual paths to each disk.

Hi,

If you look at the output of dmesg you should see where the LUNs on the SAN are mapped to the various sd devices.

That may help you too.
