Solaris SAN reference
Basic status commands:
/usr/sbin/fcinfo
cfgadm -al
ls -la /dev/rdsk/cxtx<blah>|wc -l on both nodes
Patch info for load balanced paths:
(from http://www.sunmanagers.org/pipermail/summaries/2004-July/005574.html)
1. check with array vendor (IBM) if configuration is ok for STMS (or
MPxIO, other name)
2. you need to edit /kernel/drv/scsi_vhci.conf, mpxio
is disabled by default. also you need to edit vendor/product there. look
at the comments and watch the spaces, they need to be exactly as shown
there.
Use format and inq-command to find out vendor/product.
3. you will also want to add to /etc/system:
set fp:fp_offline_ticker=15
set fp:fp_retry_count=2
with the default setting of these variables path failover takes 2
minutes, now its 45 seconds.
4. boot -r
Your devices should show in format on new controller
number with path
/scsi_vhci/ssd at g012301230123…
Richard Voss also suggested setting auto-failback=”enable” in
/kernel/drv/scsi_vhci.conf
After following these steps the SAN device now appears in format as :
nAvailable DISK SELECTIONS:
0. c1t0d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
/pci at 8,600000/SUNW,qlc at 4/fp at 0,0/ssd at w21000004cf6f1b1f,0
1. c1t1d0 <SUN36G cyl 24620 alt 2 hd 27 sec 107>
/pci at 8,600000/SUNW,qlc at 4/fp at 0,0/ssd at w21000004cf6efe8d,0
2. c5t600A0B80001323B80000000040F2051Dd0

/scsi_vhci/ssd at g600a0b80001323b80000000040f2051d
…and should multipath.
