The following information is returned:
SCSI describe of dev/rdsk/c9t1d0
vendor: hp
product: id
type: direct access
size: 10272kbytes
bytes per sector: 512
If the LUN exists, the size will reflect the capacity of the LUN. If the size returned is 0
kbytes, there is no LUN 0 created for that logical SCSI bus.
Determining LUN numbers from the hardware path
LUN numbers can be determined by using the last three segments of the VSA hardware
path, which represent the 14-bit volume number. The bits of the volume number are
encoded as shown in
.
Figure 82
VSA Volume Number Encoding
For example, if the hardware path is 8/12.8.0.0.0.3.5, the LUN number would be 29 as
shown below.
0000000 0011 101 = 00 0000 0001 1101 = 29
