To set up fiber channel shared storage

1. Shut down the cluster systems that must share the devices.

2. Install the required Fiber Channel host bus adapters on each system.

3. Cable the shared devices.

4. Reboot each system.

5. Verify that each system can see all shared devices. Use the command:

   # ioscan 
   -fnC disk

   Where "disk" is the class of devices to be shared. For example, from a system galaxy type:

   northhp# ioscan -fnC disk
   Class  I  H/W Path     Driver S/W State   H/W Type  Description
   ===============================================================
   .
   .
   disk      4  0/4/0/0.1.16.255.13.4.0  sdisk  CLAIMED     DEVICE
   SEAGATE ST318304 CLAR18 
                    /dev/dsk/c4t4d0   /dev/rdsk/c4t4d0
   disk      5  0/4/0/0.1.16.255.13.5.0  sdisk  CLAIMED     DEVICE
   SEAGATE ST318304 CLAR18   
                      /dev/dsk/c4t5d0   /dev/rdsk/c4t5d0
   .
   .

   And on another system, nebula, enter:

   south# ioscan -fnC disk
   Class  I  H/W Path     Driver S/W State   H/W Type  Description
   ===============================================================
   .
   .
   disk      4  0/4/0/0.1.16.255.13.4.0  sdisk  CLAIMED     DEVICE
   SEAGATE ST318304 CLAR18
                     /dev/dsk/c4t4d0   /dev/rdsk/c4t4d0
   disk      5  0/4/0/0.1.16.255.13.5.0  sdisk  CLAIMED     DEVICE
      SEAGATE ST318304 CLAR18 
                      /dev/dsk/c4t5d0   /dev/rdsk/c4t5d0
