Configuring virtual disks from the host
The procedure used to configure the LUN path to the array depends on the FCA driver. For more
information, see
“Installing Fibre Channel adapters” (page 78)
.
To identify the WWLUN ID assigned to the virtual disk and/or the LUN assigned by the storage
administrator:
•
Sun SAN driver, with MPxIO enabled:
You can use the
luxadm probe
command to display the array/node WWN and
associated array for the devices.
◦
◦
The WWLUN ID is part of the device file name. For example:
/dev/rdsk/c5t600508B4001030E40000500000B20000d0s2
◦
If you use
luxadm display
, the LUN is displayed after the device address. For example:
50001fe1002709e9,5
•
Sun SAN driver, without MPxIO:
The EVA WWPN is part of the file name (which helps you to identify the controller). For
example:
/dev/rdsk/c3t50001FE1002709E8d5s2
/dev/rdsk/c3t50001FE1002709ECd5s2
◦
/dev/rdsk/c4t50001FE1002709E9d5s2
/dev/rdsk/c4t50001FE1002709EDd5s2
If you use
luxadm probe
, the array/node WWN and the associated device files are
displayed.
◦
You can retrieve the WWLUN ID as part of the
format -e
(scsi, inquiry) output; however,
it is cumbersome and hard to read. For example:
09 e8 20 04 00 00 00 00 00 00 35 30 30 30 31 46 .........50001F
45 31 30 30 32 37 30 39 45 30 35 30 30 30 31 46 E1002709E050001F
45 31 30 30 32 37 30 39 45 38 36 30 30 35 30 38 E1002709E8600508
42 34 30 30 31 30 33 30 45 34 30 30 30 30 35 30 B4001030E4000050
30 30 30 30 42 32 30 30 30 30 00 00 00 00 00 00 0000B20000
◦
The assigned LUN is part of the device file name. For example:
/dev/rdsk/c3t50001FE1002709E8d5s2
You can also retrieve the LUN with
luxadm display
. The LUN is displayed after the
device address. For example:
Sun Solaris
95
