Device IDs
Device IDs identify volumes with a series of numbers and letters. The device ID acts as a substitute to identifying a volume by its name,
index, or serial number. This section describes device IDs and provides commands used to modify a device ID.
About Device IDs
When you create a volume, you must specify a volume name. When the volume is created, Storage Center assigns a unique index and
device ID to the volume and attempts to determine the volume serial number from each of its mapped servers (if the serial number is
exposed by the operating system). On subsequent commands, if you want to identify a volume, you can use:
• Volume name or index
• Device ID
• Serial number (only when running an operating system that exposes volume serial numbers to the user)
When specifying a device ID, replace the string with the device ID name or any string that contains the device ID name. For example, to
specify the device ID for a VMWare device, you can use either the device ID name (shown in bold) or the entire Universally Unique
Identier (UUID):
–deviceid 6000d31000063000000000000000001c
–deviceid 02000200006000d31000063000000000000000001c436f6d70656c
To display a volume device ID or volume serial number, use the volume show command.
Examples
The following examples illustrate how to specify the –deviceid option with various commands:
volume map command:
volume map -deviceid 6000d3100000c90000000000000000cb -server 'Ontario'
volume unmap command:
volume unmap -deviceid 000d3100000c90000000000000000c6
volume modify command:
volume modify -deviceid 000d3100000c90000000000000000cb -maxwrite 16g
volume delete command:
volume delete -deviceid 34234236000d3100000c90000000ca23423432 -purge
volume show command:
volume show -deviceid 000d3100000c90000000000000000ca -status up
replay create command:
replay create -deviceid 02000200006000d3100000c900000000000000c436f6d70656c -name 'Next Replay
