Extends the capacity of a V-VOL for Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe.
If the specified LDEV is not a V-VOL of Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe, the command is rejected with EX_ENOOBJ.
A device group can also be specified instead of an LDEV.
When the -request_id auto option is specified, if a failure occurs in a processor on an MP blade or a controller, this command cannot be run even on an MP blade or a controller on which no failure occurs.
If you specify the -request_id option for the asynchronous command, the processing is run asynchronously with the command input. Verify that the processing is complete by using the raidcom get command_status command. There is a limit to the number of asynchronous commands that can be accepted simultaneously. For details, see Maximum number of acceptable asynchronous commands.
Syntax
raidcom extend ldev {-ldev_id <ldev#> | -grp_opt <group option>
-device_grp_name <device group name> [<device name>]}
-capacity <size> | -offset_capacity <size> | -cylinder <size> [-request_id auto]
Options and parameters
- -ldev_id <ldev#> (0-65279)
-
Specifies the LDEV number (0-65279). Specify LDEVs for Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe. For example:
- -ldev_id 200
- -grp_opt <group option>
-
Specifies the device information extracted from the LDEV belonging to the device group. Specify "ldev" (fixed). The information of LDEV belonging to the device group is used.
- -device_grp_name <device group name> [<device name>]
-
Specifies the name of device group (maximum 32 characters) to be operated.
To operate an LDEV in the device group, specify the device name of LDEV (maximum 32 characters) within the device group.
If the device name is omitted, all the LDEVs belonging in the device group are operated.
- -capacity <size>
-
The increment size of capacity can be specified in bytes or blocks. When specifying in bytes, the unit is t/T (terabyte), g/G (gigabyte), m/M (megabyte), or k/K (kilobyte). If this unit is omitted, block (512 bytes) is used.
Example of specification:
1GB (gigabyte) is:
-capacity 1G, -capacity 1g, -capacity 1024M, -capacity 1024m, -capacity 1048576K, -capacity 1048576k, -capacity 2097152
- -offset_capacity <size>
-
Specifies capacity. Corrects the size as well as GUI for the specified capacity. The capacity can be specified in bytes or blocks.
- -cylinder <size>
-
Specifies the size in cylinder unit. When specifying, the unit is g/G (gigabyte), m/M (megabyte), or k/K (kilobyte). Cylinder is applied if you do not specify the unit.
When the emulation type for the Open System is specified, this option cannot be specified.
- -request_id auto
-
(VSP 5000 series, VSP G1x00, VSP F1500and VSP G130, G/F350, G/F370, G/F700, G/F900 only) Specifying this option is recommended when running the command. Specify this option to expand the capacity of a DRS-VOL. <request#> is a Request ID assigned each time the command is run. For more information, see Request ID function.
If you refresh the Device Manager - Storage Navigator window during the capacity expansion of a DRS-VOL, refreshing the window might not be performed. For more information, see the Troubleshooting section in the System Administrator Guide.
Examples
