To change a storage pool, complete the following fields and then click Finish, or click Cancel to end this task.
Enter the description of the storage pool to be updated. This parameter is optional. The maximum length of the description is 255 characters.
Select the appropriate access authority for users and system processes to access the files in the storage pool. This parameter is optional.
Readwrite | Specifies that users and system processes (like migration) can read and write to files stored on volumes in the storage pool. Readwrite is the default. |
Readonly | Specifies that users can only read files from the volumes in the storage pool. |
Unavail able | Specifies that users cannot access files stored on volumes in the storage pool. |
Enter the maximum physical file size for a file to be stored in storage pool. This parameter is optional. Specify a number (1 to 999999) followed by a scale factor, or Nolimit. Scale factors and their meanings are:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
T | Terabyte |
Select an appropriate storage pool to which files can be migrated. A pool specified with this parameter must be a primary storage pool. A copy storage pool cannot be specified. This parameter is optional. If no value is specified for this parameter, migration cannot occur and files that exceed the value specified in the Maximum Size Threshold parameter cannot be placed in another storage pool. The default is blank.
Enter the percentage of storage pool occupancy that specifies when ADSM can start migration for this storage pool.
Enter the percentage of storage pool occupancy to determine when ADSM can stop migration for this storage pool.
Select an option to determine whether a cached copy of a file that has been migrated remains in the disk storage pool. This parameter is optional.
Yes | Specifies that a caching is enabled and a cached copy of a migrated file remains in the disk storage pool. |
No | Specifies that caching is disabled and no cached copy of a migrated file remains in the disk storage pool. No is the default. |
Enter the number of processes that are used for migrating files from this storage pool. This parameter is optional.
Enter the number of days a file must remain in a storage pool before the file is eligible for migration from the storage pool. The number of days is counted from the day the file was last stored in the storage pool or retrieved by a client, or whichever is more recent.
Select an option to determine whether ADSM is allowed to migrate files that do not satisfy the migration delay time. This parameter is optional. The default is yes.
Because you can require that files remain in the storage pool for a minimum number of days, ADSM may migrate all eligible files to the next storage pool yet not meet the low migration threshold. Selecting yes or no determines if ADSM is allowed to continue migrating files that do not satisfy the migration delay time.
Yes | Specifies that when necessary to meet the low migration threshold, ADSM continues to migrate files that do not satisfy the migration delay time. |
No | Specifies that ADSM stops migration when no eligible files remain to be migrated, even before reaching the low migration threshold. ADSM does not migrate files unless the files satisfy the migration delay time. |
