Checking MPxIO Multipath Status
Use the "format" command to check the MPxIO multipath status after multipathing is set up
(example output follows).
Example: ETERNUS8000
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1t0d0 <SUN146G cyl 14087 alt 2 hd 24 sec 848>
/pci@8,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0113ce2e1,0
1. c7t6000B5D0006A0000006A010900000000d0 <FUJITSU-E8000-0000 cyl 6248 alt 2 hd 64
sec 256>
Use the "luxadm" command to check that each path in the multipath configuration is normal.
Example: ETERNUS8000
# luxadm display /dev/rdsk/c7t6000B5D0006A0000006A010900000000d0s2
