rmpool

Removes a VOB storage pool

APPLICABILITY

Product	Command type
ClearCase	cleartool subcommand

Platform
UNIX
Windows

SYNOPSIS

rmpool [ –c·omment comment | –cfi·le comment-file-pname | –cq·uery: | –cqe·ach | –nc·omment ] pool-selector ...

DESCRIPTION

The rmpool command deletes one or more storage pool directories from a VOB, along with all the data container files stored within them.

Reassigning Elements

Before removing a storage pool, you must reassign all its currently assigned elements to a different pool, using the chpool command. Otherwise, rmpool aborts with an elements using pool error. To list all the elements in a source or cleartext pool, use a find command. For example

UNIX
cmd-context find -all -element 'pool(source_2)' –print
Windows
cmd-context find -all -element pool(source_2) –print

This command does not work with derived object pools.

Deleting Derived Object Pools

There is no way to move a shared derived object from one pool to another. Thus, you can delete a derived object pool only if either condition is true:

No directory elements have been assigned to the pool.
All data containers in the pool have been removed by the scrubber program or rmdo commands, and each directory element that currently uses the pool has been assigned to a different derived object pool.

RESTRICTIONS

Identities

You must have one of the following identities:

Pool owner
VOB owner
root (UNIX)
Member of the ClearCase administrators group (Windows)

Locks

An error occurs if one or more of these objects are locked: VOB, pool.

Mastership

(Replicated VOBs only) No mastership restrictions.

OPTIONS AND ARGUMENTS

Event Records and Comments

Default: Creates one or more event records, with commenting controlled by your .clearcase_profile file (default: –nc). See the comments reference page. Comments can be edited with chevent.
–c·omment comment | –cfi·le comment-file-pname |–cq·uery | –cqe·ach | –nc·omment: Overrides the default with the option you specify. See the comments reference page.

Specifying the Pools to Be Removed

Default

Removes a pool from the VOB containing the current working directory unless you specify another VOB with the @vob-selector suffix.

pool-selector ...

One or more names of existing storage pools. Specify pool-selector in the form [pool:]pool-name[@vob-selector]

pool-name	Name of the storage pool
vob-selector	VOB specifier. Specify vob-selector in the form [vob:]pname-in-vob
	pname-in-vob	Pathname of the VOB tag (whether or not the VOB is mounted) or of any file system object within the VOB (if the VOB is mounted)

EXAMPLES

The UNIX examples in this section are written for use in csh. If you use another shell, you may need to use different quoting and escaping conventions.

The Windows examples that include wildcards or quoting are written for use in cleartool interactive mode. If you use cleartool single-command mode, you may need to change the wildcards and quoting to make your command interpreter process the command appropriately.

In cleartool single-command mode, cmd-context represents the UNIX shell or Windows command interpreter prompt, followed by the cleartool command. In cleartool interactive mode, cmd-context represents the interactive cleartool prompt.

Change all elements using the c_source_pool to use the default source pool (sdft) instead. Then, delete c_source_pool.
cmd-context  find . –all –element 'pool(c_source_pool)' \
–exec 'cleartool chpool –force sdft $CLEARCASE_PN'Changed pool for "/usr/hw/src" to "sdft". Changed pool for "/usr/hw/src/libutil.a" to "sdft".   . . .

cmd-context  rmpool c_source_pool
Removed pool "c_source_pool".
