Modifying an extent pool

Complete this task to modify the properties of an extent pool using the DS CLI application.

1. Issue the lsextpool command to generate a report that identifies the status of your extent pools by storage type (fixed block or count key data). Enter the lsextpool command at the dscli command prompt with the following parameters and variables:

   dscli>lsextpool -dev storage_image_ID -l -stgtype (fb | ckd)

   Note: The -stgtype parameter must be designated as either fb (fixed block) or ckd (count key data). The storage type allows you to limit the list of extent pools for issues such as which ones to rename or to change the limit or threshold percentages.
2. Issue the chextpool command to change the name that is assigned to the extent pool or to change the percentages that are allocated for extent and threshold limits. Enter the chextpool command at the dscli command prompt with the following parameters and variables:

   dscli>chextpool -dev storage_image_ID -name new_extent_pool_name
   -extentlimit [on | off] -limit extent_limit_percentage 
   -threshold extent_threshold_percentage -extentpool_ID

   Notes:

   1. The new extent pool name can include up to sixteen characters.
   2. The -extentpool_ID parameter is required but does not need to be specified as a separate entry. You can add it to the storage_image_ID parameter. For example: IBM.1750-68FA120/P21, with P21 being the extent pool ID. Extent pool IDs are specified as 4-digit values with no leading zeros, and they are preceded by the letter P.
   3. The unique name that you assigned to the extent pool does not display in the output message of the chextpool command. However, when you issue the lsextpool command, the extent pool name is displayed.
3. Issue the lsextpool command to verify that your changes have been processed.
