To define a sequential access primary storage pool, complete the following fields and then click Finish, or click Cancel to end the task.
Enter a name for the storage pool. The name is required. The maximum length of the name is 30 characters.
Select the device class that the storage pool will use.
Enter a description of the storage pool. The maximum length of the description is 255 characters.
Select how client nodes and server processes (such as migration and reclamation) can access files in the storage pool. The default is Readwrite.
Readwrite | Specifies that both client nodes and server processes can read and write to files stored on volumes in the storage pool. |
Readonly | Specifies that client nodes can only read files from the volumes in the storage pool. Server processes can move files among volumes in the storage pool, but cannot write new files. |
Unavail able | Specifies that client nodes cannot access files stored on volumes in the storage pool. Server processes can move files among volumes in the storage pool, but cannot write new files. Server processes can also move or copy files from this storage pool to another storage pool. |
Enter the maximum physical size of a file to be stored in the storage pool during a session with a client node. Enter a number (1 to 999999) followed by a scale factor, or enter NOLIMIT. The default is NOLIMIT. Scale factors and their meanings are:
K | Kilobyte |
M | Megabyte |
G | Gigabyte |
T | Terabyte |
For example, enter 5G to set the maximum file size to 5 gigabytes.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
The format in which data will be stored. The data format used can determine what parameters are available and what options are available for those parameters.
Native | Specifies that the data format is the native Tivoli Storage Manager server format. |
Netappdump | Specifies the data is in a NetApp dump format. This format should be specified for file system images that are in a dump format and that have been backed up from a Network Appliance file server using TDP for NDMP. The server will not perform storage pool backup, migration, reclamation, MOVE DATA, and AUDIT VOLUME for a storage pool with DATAFORMAT=NETAPPDUMP. |
Select a primary storage pool to which the server can migrate files from this storage pool.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Enter the percentage of storage pool occupancy that specifies when the server can start migration for this storage pool. The default is 90.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Enter the percentage of storage pool occupancy to determine when the server can stop migration for this storage pool. The default is 70.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Select whether the server attempts to keep data belonging to a single client node or to a single client node's file space on as few volumes as possible. The default is No.
Yes | Specifies that collocation is enabled. The server tries to put data for one node on as few volumes as possible. The server does not try to collocate data by file space. |
No | Specifies that collocation is disabled. |
Filespace | Specifies that collocation is enabled at the file space level for client nodes. The server tries to put data for one node and file space on as few volumes as possible. If a node has multiple file spaces, the server tries to put data for different file spaces on different volumes. |
Enter the percentage of reclaimable space on a volume to specify when the server starts reclamation of fragmented space on volumes in the storage pool. The default is 60.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Enter the maximum number of scratch volumes that can be requested by the server for this storage pool. The default is 0.
Enter the number of days (0 to 9999) that must elapse after all files have been deleted from a volume, before the volume can be rewritten or returned to the scratch pool. The default is 0.
Select another storage pool as a target for data from reclaimed storage pool volumes. By default, the server moves data from reclaimed volumes to other volumes in the same storage pool.
You may want to select a storage pool for reclaiming data if the library for the storage pool has only one drive.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Enter the overflow location for the storage pool. This applies to storage pools associated with automated libraries only. The maximum length is 255 characters.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Enter the number of days that 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. The default is 0, which means migration will not be delayed. The number must be an integer from 0 to 9999.
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
Select whether to allow the server to migrate files that do not satisfy the migration delay time. The default is Yes.
Because you can require that files remain in the storage pool for a minimum number of days, the server may migrate all eligible files to the next storage pool yet not meet the low migration threshold. Selecting yes or no determines if the server 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, the server continues to migrate files that do not satisfy the migration delay time. |
No | Specifies that the server stops migration when no eligible files remain to be migrated, even before reaching the low migration threshold. The server does not migrate files unless the files satisfy the migration delay time. |
Note: For storage pools with DATAFORMAT=NETAPPDUMP, this parameter is unavailable.
