Displaying The Size Of A Local Disk; Displaying Installed Devices And Attributes; Displaying Additional Device-Specific Information - IBM TotalStorage NAS Gateway 500 Administrator's Manual

Displaying the size of a local disk

To display the size of a local storage device, use the NAS command, lspvol, to
view the attributes for the disk. The attributes for a storage device are displayed by
specifying the name of the device.
For example, to determine the size of hdisk2:
$ lspvol hdisk2
An example of the output from executing this command is:
hdisk2

Note: The size information is in bold for emphasis.

Displaying installed devices and attributes

To view the installed devices on a system, use the NAS command lscfg. By default,
it displays the devices configured in the system. If you specify options, you can
obtain information about a specific device, such as the World Wide Name (WWN)
or the ROS level (firmware). See "Displaying additional device-specific information"
for more information.
CLI command
At the command prompt, enter the lscfg command.
This displays the devices in the system configuration. For example, to display
additional information for a fibre-channel adapter, enter: lscfg -vl fcs0.
SMIT fastpath
The SMIT fastpath to view the configured disks is smit lscfg.
WebSM
To view the Vital Product Data (VPD) for a device, do the following: NAS
Management→NAS System→ Node (Server IP Address) →Devices→ Disks.

Displaying additional device-specific information

In order to display additional information for a device (for example, a fibre-channel
adapter), use the NAS command lscfg.
CLI command
At the command prompt, enter lscfg. This displays the devices in the system
configuration.
Use the -v flag to display vital product data.
