2. Physical address description
A SCSI address may be changed by rebooting a server. By contrast, physical address
description uses physical location information not affected by such a case.
An example is shown below.
P:3f:0:0003000433204223:1:0:3
Leading character "P" is the symbol that represents the description is physical
address one. And the items after "P" are PCI bus number, PCI slot number, serial
number of storage unit, host director number of storage unit, port number of host
director and logical disk identifier.
Omitted items are treated as wildcard like as SCSI address description.
Storage Processor should be specified instead of host director number. And logical
unit identifier can not be used, therefore logical unit identifier is always treated as
wildcard. An example is shown below.
P:3f:0:SLES3000433204223:A:0:
And the following format can be accepted. Omitted items are treated as wildcards.
--busid 0000:3f:09.0 --serial 0003000433204223 --hd 1 --port 3
3. Logical disk description
This format is used to specify a logical disk.
If this description is used for a option that affects per path, such as "--active", all the
paths on the specified logical unit are set into target.
The following two formats can be accepted in logical disk description.
D:0003000433204223:3
D:12:34:56:78:90:12:34:55:67:78:23:12:45:67:34:12
Leading character "D" is the symbol that represents the description is logical disk
one.
In the upper one, two items are serial number of storage unit and logical disk number.
But, logical disk number can not be used as same as the physical address description.
To specify the logical disk on Overland SnapSAN S3000/S5000, use the lower
description. It consists of only logical disk identifier (LunWWN).
And the following format can be accepted
--lunwwn 00:00:00:00:00:00:00:00
4. Device file description
This format is described with a device file name (/dev/sdX, dev/ddX). Only the device
file beginning with "/dev/sd" or "/dev/dd" can be accepted. If the device file is described
with "/dev/sd", the target is a corresponding path. If described with "/dev/dd", the
target is a corresponding logical disk.
To specify the plural device files, enumerate the device file names or use wildcard.
5. Path number description
This format is described with a path number (decimal integer).
[command mapping with older version]
The following table shows the command examples to handle the several cases using newer
command (spsadmin) and older command (spscmd).
