Sun Solaris 9 Commands to Connect SAN Disks

$ man luxadm

Maintenance Commands luxadm(1M)

NAME
luxadm - administration program for the Sun Enterprise Net-
work Array (SENA), RSM, SPARCstorage Array (SSA) subsystems,
and individual Fiber Channel Arbitrated Loop (FC_AL) devices

SYNOPSIS
luxadm [ options ... ] subcommand [ options ... ] enclo-
sure [ ,dev ] | pathname ...
-----------------------------------------


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

Here are some of the commands I use, also attached stuff for old ssa.

FCAL Disks
luxadm probe (discovers fcal)
luxadm display Enclosure (displays information on fcal box)
luxadm reserve /dev/rdsk/c#t#d#s# (reserves device so it can’t be accessed)
luxadm -e offline /dev/rdsk/c#t#d#s# (takes a device offline)
luxadm -e bus_quiesce /dev/rdsk/c#t#d#s# (quiesce the bus)
luxadm -e bus_unquiesce /dev/rdsk/c#t#d#s# (unquiesce the bus)
luxadm -e online /dev/rdsk/c#t#d#s# (bring the disk device back online)
luxadm release /dev/rdsk/c#t#d#s# (unreserved the device for use)
luxadm remove_device BAD,f2 (removes a device from slot f2 on enclosure BAD)
luxadm insert_device BAD,f2 (hot plug a new device to slot f2 on enclosure BAD)

SSAADM (for old ssa drawers)
ssaadm display c# (displays ssa on controller)
ssaadm display /dev/rdsk/c#t#d#s# (display drive information)
ssaadm start /dev/rdsk/c#t#d#s# (spin up a specific drive)
ssaadm stop /dev/rdsk/c#t#d#s# (spin down a specific drive)
ssaadm start –t 3 c# (spin up all drives in tray 3 on controller )
ssaadm stop –t 3 c# (spin down all drives in tray 3 on controller)
ssaadm start c# (spin up all drives in array)
ssaadm stop c# (stop all drives in array)
