match up ssd device with c?t?d?

Post by Frank Jendrasz » Sun, 21 Apr 1996 04:00:00



How do I match up the output of iostat -xtc (ie.)

ssd16
ssd17

with my device names under my sparc 100 arrays?

I know I can get this:

ssd16 at SUNW,pln0: target 0 lun 0
ssd17 at SUNW,pln0: target 1 lun 0      
ssd18 at SUNW,pln0: target 2 lun 0

But which physical disk is that? What controller? Target?

Thanks,

Frank

This *IS* a pain.  The only way i know to do this is to match up the ssd messages
in dmesg or /var/adm/messages* with the symbolic links in /dev/dsk.  Its good to
have a table matching up the ssd numbers with c?t?d?s* when the kernel starts
kicking out disk error messages!
