Sun Solaris 9 Commands to Connect SAN Disks

There are always a bunch of strange commands to connect a server to SAN disks. In my case, I’m running Solaris 9, using QLogic Fibre Channel cards, and connecting to an IBM DS4300.

1) Connect the Solaris server SAN disks. After I made the connection, the GUI that allows me to zone the SAN recognized the QLogic connections, and I zoned the LUNs.

If you need more detailed instructions, here are some potentially useful posts: How to Zone a Brocade SAN Switch and How to Zone IBM DS4000 SAN Disks.

2) Scan your disks, and it should show up as a new disk when you run “format”.

Solaris# devfsadm
Solaris# format

My result: No new disks. Sigh.

3) Run a bunch of cryptic but useful diagnostic commands:

To see your HBA ports and whether you’re connected:

Solaris# luxadm -e port
Found path to 3 HBA ports
/devices/pci@8,700000/SUNW,qlc@2/fp@0,0:devctl CONNECTED
/devices/pci@8,700000/SUNW,qlc@2,1/fp@0,0:devctl CONNECTED
/devices/pci@8,600000/SUNW,qlc@4/fp@0,0:devctl CONNECTED

To see your disks:

Solaris# luxadm probe

To see your HBA ports (type fc-private, below) and their connected disks (type disk):

Solaris# cfgadm -al

Ap_Id Type Receptacle Occupant Condition
c8 fc-private connected configured unknown
c8::200800a0b8199b3b disk connected configured unknown
c9 fc-private connected configured unknown
c9::200900a0b8199b3b disk connected configured unknown

4) Force Fibre Channel SAN disk rescan, since everything looks connected and okay. Use your device path from “luxadm -e port” output.

Solaris# luxadm -e forcelip /devices/pci@8,700000/SUNW,qlc@2/fp@0,0:devctl
Solaris# luxadm -e forcelip /devices/pci@8,700000/SUNW,qlc@2,1/fp@0,0:devctl
Solaris# luxadm -e forcelip /devices/pci@8,600000/SUNW,qlc@4/fp@0,0:devctl

5) Rerun format command.

Solaris # format
