HP StorageWorks P9000 Command View Advanced Edition Suite Software 7.1.1 Administrator Guide (web) (TB581-96065, September 2011)

ValueSetting item
Specify the command device identifier (the PhysicalDrive number,
VolumeGUID, or device file name) that the host recognizes in the
following format:
#
• In Windows:
\\.\PhysicalDriveX
\\.\Volume{GUID}
• In Linux:
/dev/sdX
X is an integer.
deviceFileName
#:
• If this item is specified using the physical drive number in Windows or Linux and you then restart
the OS, the physical drive number and device file name might be changed. If this occurs, you
need to execute the perf_findcmddev command to check and update the settings. In Windows,
if you specify this item using the volume GUID, the setting is not affected even if you restart the
OS.
• If you are using the Device Manager agent version 6.3 or earlier and you want to acquire per-
formance information of all SLPRs in an SLPR environment, you need to define SLPR0 command
device in the perf_cmddev.properties file.
To define command devices for different SLPRs that belong to the same storage system, define the
SLPR0 command device in the first line of the storage system. The following example shows how
to define PhysicalDrive5 (whose LDEV number is 345) as the SLPR0 command device of
XP12000/XP10000/SVS200 (whose serial number is 14050).
R600.44332.456: \\.\PhysicalDrive3
R500.14050.345: \\.\PhysicalDrive5
R500.14050.346: \\.\PhysicalDrive6
R500.14050.347: \\.\PhysicalDrive10
R501.89832.780: \\.\PhysicalDrive15
Format of the perf_findcmddev command
The perf_findcmddev command allows you to specify a command device in the
perf_cmddev.properties file.
To execute this command, you must have Administrator permissions (for Windows) or root permissions
(for Linux).
The format of the perf_findcmddev command is as follows:
In Windows:
installation-folder-for-the-Device-Manager-agent\bin\perf_findcmddev
{ view | verify | write [-file file-name] }
In Linux
installation-directory-for-the-Device-Manager-agent/bin/perf_findcmddev
{ view | verify | write [-file file-name] }
The parameters for the perf_findcmddev command are described below.
