HP P9000 Command View Advanced Edition Suite Software 7.3.1-00 Administrator Guide (web)

DetailsItem
The hldutil command is used to acquire information on storage system LDEVs, file
systems, and other devices. It also allows you to output the acquired information to an
execution log file and to view past execution log files. If all options are omitted,
information is output about all LDEVs recognized by the host.
This operation requires Administrator or superuser privileges. If the OS is Windows
Server 2008 or Windows Server 2008 R2, the command must be executed from a
command prompt started as an Administrator.
Caution: If you execute the hldutil command immediately after the host environment
is changed (for example, after an LU is added or deleted), the command might not be
able to recognize the changed contents of the host. In this case, wait a while, and then
re-execute the hldutil command.
Description
-d [device-number-or-device-file-name]
To view information about a specific LDEV, specify the drive number (in Windows)
or device special file name (in UNIX) of the LDEV. If you omit this option, the
command displays information about all currently recognized LDEVs. You cannot
specify the -d option and the -g or -l option at the same time.
Options
-g [drive-group-name]
If you want to view information about a specific drive group, specify the name of
the drive group. If you omit the drive group name, the command outputs information
about all currently defined drive groups. You cannot specify the -g option and the
-d or -l option at the same time.
-l ldev-number.serial-number
If you want to view information about a specific LDEV, specify the LDEV number
(LDEV#) and serial number (serial#) of the LDEV. The LDEV number and serial
number must be specified in the indicated order. If you omit the LDEV number or
serial number, the command does not output information about the LDEV. You
cannot specify the -l option and the -d or -g option at the same time. If you
specify the -l option, only the following items are output:
Ldev# (LDEV number)
Ser# (storage system serial number)
Device (device special file name or drive number)
Dg name (drive group name)
fs (file system)
-p
Specify this option to add the P-VOL and S-VOL information (that you set up by
using Business Copy, Continuous Access, Snapshot or Continuous Access Journal)
to the drive information to be output. When this option specified, if no P-VOL or
S-VOL information is assigned to an LDEV, nothing is output.
-q
Specify this option to output the command execution results only to the execution
log file without sending them to the standard output (quiet mode). Typically, you
specify this option when you want to run a background job to output the latest
LDEV information to the execution-result log file. However, error messages are sent
to the standard error output.
-nolog
Specify this option to send the command execution results only to the standard
output without updating the execution log file.
