Hi,
I asked how to map a disk to a position on the A5000 disk array.
My thanks to all of the following:
Keating, Peter <PKeating@mits.com.au
Edan Idzerda <edan@mtu.edu>
Bliss, Kevin <Kevin.Bliss@nike.com>

Whiffen, Richard <whiffen@ici.org>
Schave, Jeff <jeff.schave@tdstelecom.com>
I'm illustrating all possible permutations with an example below:
If this is the message from /var/adm/messages:
WARNING: /pci@4,4000/SUNW,ifp@4/ssd@w2100002037143e55,0 (ssd15)
^^^^^^^^^^^^^^^^^
To map to controller and target number
--------------------------------------
# format
13. c2t18d0 <SUN9.0G cyl 4924 alt 2 hd 27 sec 133>
/pci@4,4000/SUNW,ifp@4/ssd@w2100002037143e55,0
Now we know ssd@w2100002037143e55,0 maps to c2t18d0.
To map this to a veritas disk
-----------------------------
# vxdisk list
c2t18d0s2 sliced disk01 diskgrp-name online
To get the name of the array
----------------------------
# luxadm probe
Found Enclosure(s):
SENA Name:RAIDNAME Node WWN:123456789
Logical Path:/dev/es/ses0
Logical Path:/dev/es/ses1
To map the disk to a position on the A5000
------------------------------------------
Use the RAIDNAME from above:
# luxadm display RAIDNAME
SLOT FRONT DISKS (Node WWN) REAR DISKS (Node WWN)
2 On (O.K.) 200000203714012a On (O.K.)
2000002037143e55
By searching for the last 5 or so numbers (43e55) on the wwn (world wide
name), we see the disk we're looking for is in the rear in slot 2.
To map position on A5000 to disk name
-------------------------------------
# luxadm display RAIDNAME,r2
/dev/rdsk/c2t18d0s2
/devices/pci@4,4000/SUNW,ifp@4/ssd@w2100002037143e55,0:c,raw
i.e. 'luxadm disp RAIDNAME,f[0-7]' or 'luxadm disp RAIDNAME,r[0-7]'
To map disk name to wwn name and array name
-------------------------------------------
# luxadm display /dev/rdsk/c2t2d0s2
To map disk name to wwn
-----------------------
# ls -l /dev/rdsk/c2t2d0s2
lrwxrwxrwx 1 root root 65 Dec 20 20:15 /dev/rdsk/c2t2d0s2 ->
../../devices/pci@4,4000/SUNW,ifp@4/ssd@w210000203714012a,0:c,raw
