Listing Classes, Devices, Paths, and Volumes
There are four I/O configurator commands that list objects: LCLASS,
LDEV, LPATH, and LVOL.
Listing Classes
The LCLASS command lists the class names, class modes, and the devices
associated with the classes as they apply to the I/O configuration.
LCLASS has the following parameters:
LCLASS (LC) [ [CLASS =] classname,...]
[ [DEST =] OFFLINE]
The CLASSNAME parameter specifies the class which LCLASS lists. To see
the assigned LDEVs of a particular device class, enter:
io>LCLASS classname
Specify multiple classes by surrounding them by parentheses and
separating them with commas. To list the assigned LDEV numbers of
combined classes, enter:
io>LCLASS (classname1, classname2)
To list all the classes assigned to all configured LDEVs enter:
io>LCLASS
Listing Devices
Each configured logical device (LDEV) has a uniquely assigned LDEV
number. An LDEV number identifies a physical device associated with a
system.
The LDEV command lists the characteristics of the I/O devices configured
for the system. If no parameters are specified, all the I/O devices and
their characteristics are listed. The LDEV command has the following
syntax:
LDEV (LD) [ [LDEV =] device range]
[ [ID = ] product number]
[ [TYPE = ] device type]
[ [CLASS = ] classname,...]
[ [DEST = ] OFFLINE]
You may enter more than one parameter. To enter multiple parameters for
CLASS, enter
io>LDEV CLASS=(classname1,classname2,...)
To list all configured devices, enter LDEV without any parameters:
io>LDEV
You can list devices with the specified identification number:
io>LDEV ID=HP7937H
To specify a consecutive range, use the following format:
io>LDEV first device number/last device number
Enclose nonconsecutive ranges in parentheses. For example:
io>LDEV (4/9,11,14)
Listing Paths
The LPATH command displays information concerning the adapters and I/O
devices on a specified path level. The command lists the configured I/O
paths according to their path, hierarchy level, or associated I/O
manager.
LPATH has the following parameters:
LPATH (LP) [ [PATH = ] path]
[ [LEVEL = ] #]
[ [MANAGER = ] manager-name,...]
[ [DEST = ] OFFLINE]
Listing Volumes
The LVOL command lists the associated device number and the virtual
storage allocation for a system volume. The LVOL command has the
following parameters:
LVOL (LV) [ [VNAME = ] volume name,...]
[ [DEST = ] OFFLINE]
To list volume information, enter LVOL volume name or LVOL to list
information for all volumes.
io>LVOL volumename
io>LVOL
SYSGEN displays the LDEV number of each device, the amount of transient
and permanent space, and the volume class.
