rmsestg
The rmsestg command deletes the specified repositories in an extent pool.
Parameters
- -dev storage_image_ID
- (Optional) The storage image ID, which consists of a value for manufacturer, machine type, and serial number. The storage image ID is required if you do not specify a fully qualified ID for the extent pool ID, do not set the devid variable in your profile or through the setenv command, and the HMC is aware of more than one storage image. Using the -dev parameter will temporarily override any defined value for devid for the current command.
- -reptype all | tse | ese
- (Optional) The type of repository to remove. If the type is not specified, the default is
all.
Valid repository types are as follows:
- all
- The removal of all physical repositories, plus any overhead that is used to manage the virtual capacity. However, if no ESE volumes exist after this action but are later created, the virtual capacity overhead is automatically re-created.
- tse
- The removal of the physical TSE repository in an extent pool. Any ESE repository and virtual
capacity overhead remain unchanged. Notes:
- Using this option is equivalent to using the chsestg command and setting the TSE repository capacity to zero (0).
- A TSE repository is required to create TSE volumes. Starting with DS8000®, Release 8, TSE repositories can no longer be created.
- All TSE volumes must be removed before attempting to remove the TSE repository.
- ese
- The removal of the physical ESE repository in an extent pool. Any TSE repository and virtual
capacity overhead remain unchanged.Notes:
- An ESE repository is not required to create ESE volumes.
- Removing the ESE repository allows the entire pool to be used by any requestor of that capacity whether it is for standard volumes, a TSE repository, virtual capacity (overhead), or ESE volumes. That is, the ESE volumes have 0% of the pool guaranteed, and the extent limit of the pool is allowed)
- -quiet
- (Optional) Turns off the space-efficient storage removal confirmation prompt for this command.
- extentpool_ID ... | -
- (Required) The IDs of one or more extent pools that you want to delete the space-efficient storage from. A fully qualified extent pool ID is accepted, which consists of the storage image ID or a shortened version without the storage image ID if the -dev parameter is specified. The shortened version is a four-decimal digit number with no leading zeroes, prefixed with the letter P.
Example: Creating space-efficient storage in an extent pool
dscli> rmsestg -dev IBM.2107-75FA120 P2
Output
Are you sure that you want to delete the space-efficient storage for the extent pool P2?[Y/N]: The space-efficient storage for the extent pool P2 has been deleted successfully.
