The following table lists the recording formats and estimated capacities
for 3570 devices:
Table 51. Recording Format and Default Estimated Capacity for 3570 Tape Volumes
Format | Estimated Capacity | Description |
---|---|---|
DRIVE | -- | The server selects the highest format that is supported by the drive on
which a volume is mounted.
Attention: Avoid specifying DRIVE when a mixture of drives is used within the same library. For example, do not use this option for a library containing some drives that support recording formats superior to other drives. |
3570B | 5.0GB | Uncompressed (basic) format |
3570C |

| Compressed format |

You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
You must specify this value as an integer followed by K (Kilobytes), M (Megabytes), or G (Gigabytes). The smallest value allowed is 100KB (that is, ESTCAPACITY=100K).
For example, ESTCAPACITY=5M specifies that the estimated capacity for a volume in this device class is 5 megabytes.
For more information on the default estimated capacity for 3570 cartridge tapes, see Table 51.
If you have already established a media label naming convention that supports your current management system, use a volume prefix that conforms to your naming conventions.
Values specified for this parameter must meet the following conditions:
AB.CD2.E
An example of a tape volume data set name using the default prefix is ADSM.BFS.
This parameter can improve response time for sequential access media mounts by leaving previously mounted volumes online. However, for EXTERNAL library types, setting this parameter to a low value (for example, two minutes) enhances device sharing between applications.
The following are possible values:

Attention: If you specify DRIVE for a device class that has non-compatible sequential access devices, then you must mount volumes on devices that are capable of reading or writing the format established when the volume was first mounted. This can cause delays if the only sequential access device that can access the volume is already in use.

You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
You must specify this value as an integer followed by K (Kilobytes), M (Megabytes), or G (Gigabytes). The smallest value allowed is 100KB (that is, ESTCAPACITY=100K).
For example, ESTCAPACITY=5M specifies that the estimated capacity for a volume in this device class is 5 megabytes.
For more information on the default estimated capacity for cartridge tapes, see Table 58.
If you have already established a tape label naming convention that supports your current tape management system, use a tape volume prefix that conforms to your naming conventions.Values specified for this parameter must meet the following conditions:
AB.CD2.E
ADSM.BFS is an example of a tape volume filename using the default prefix and the added server qualifier.
This parameter can improve response time for sequential access media mounts by leaving previously mounted volumes online. However, for EXTERNAL library types (that is, a library managed by an external media management system), set this parameter to a low value (for example, two minutes) to enhance device sharing between applications.
The following are possible values:

The maximum value is 128GB (MAXCAPACITY=128G).
By specifying a directory name, you identify the location where the server places the files that represent storage volumes for this device class.
Later, if the server needs to allocate a scratch volume, it creates a new file in this directory. For scratch volumes used to store client data, the file created by the server has a file name extension of .BFS. For scratch volumes used to store export data, a file name extension of .EXP is used. For example, if you define a device class with a DIRECTORY of c:\smstor and the server needs a scratch volume in this device class to store export data, the file that the server creates may be named c:\smstor\00566497.exp.
Examples
Task
Define a device class named PLAINFILES with a FILE device type and a maximum capacity of 50MB.
define devclass plainfiles devtype=file maxcapacity=50m
When using this device type, the server does not recognize either the type of device or the cartridge recording format. Because the server does not recognize the type of device, if an I/O error occurs, error information is less detailed compared to error information for a specific device type (for example, 8mm). When defining devices to the server, do not mix various types of devices within the same device type.
Privilege Class
To issue this command, you must have system privilege or unrestricted storage privilege.

The server recognizes that the media can be removed and that additional media can be inserted, subject to limits set with the MOUNTLIMIT parameter for the device class and the MAXSCRATCH parameter for the storage pool.
Volumes in a device class with device type GENERICTAPE are sequential access volumes.
You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
Specify a capacity appropriate to the particular tape drive being used.
You must specify this value as an integer followed by K (Kilobytes), M (Megabytes), or G (Gigabytes). The smallest value allowed is 100KB (that is, ESTCAPACITY=100K).
For example, ESTCAPACITY=5M specifies that the estimated capacity for a volume in this device class is 5 megabytes.
This parameter can improve response time for sequential access media mounts by leaving previously mounted volumes online. |However, for EXTERNAL library types, setting this parameter to a low |value (for example, two minutes) enhances device sharing between |applications.

You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
You must specify this value as an integer followed by K (Kilobytes), M (Megabytes), or G (Gigabytes).
For example, ESTCAPACITY=100G specifies that the estimated capacity for a volume in this device class is 100 gigabytes.
For more information on estimated capacities, see Table 59.
If you have already established a media label naming convention that supports your current management system, use a volume prefix that conforms to your naming conventions.
Values specified for this parameter must meet the following conditions:
AB.CD2.E
An example of a tape volume data set name using the default prefix is ADSM.BFS.
This parameter can improve response time for sequential access media mounts by leaving previously mounted volumes online. However, for EXTERNAL library types, you can enhance device sharing between applications by settting this parameter to a low value (for example, two minutes).
The following are possible values:

You can specify this parameter if the default estimated capacity for the device class is inaccurate due to compression of data.
You must specify this value as an integer followed by K (Kilobytes), M (Megabytes), or G (Gigabytes). The smallest value allowed is 100KB (that is, ESTCAPACITY=100K).
For example, ESTCAPACITY=5M specifies that the estimated capacity for a volume in this device class is 5 megabytes.
For more information on the default estimated capacity for QIC tapes, see Table 61.
If you have already established a media label naming convention that supports your current management system, use a volume prefix that conforms to your naming conventions.
Values specified for this parameter must meet the following conditions:
AB.CD2.E
An example of a tape volume data set name using the default prefix is ADSM.BFS.
This parameter can improve response time for sequential access media mounts by leaving previously mounted volumes online. However, for EXTERNAL library types (that is, a library managed by an external media management system), set this parameter to a low value (for example, two minutes) to enhance device sharing between applications.

The server recognizes that the media can be removed and that additional media can be inserted, subject to limits set with the MOUNTLIMIT parameter for the device class and the MAXSCRATCH parameter for the storage pool.
Volumes in a device class with device type REMOVABLEFILE are sequential access volumes.
When using CD-ROM media for the REMOVABLEFILE device type, the library type must be specified as MANUAL. Access this media through a drive letter, for example, E:. Use the device manufacturer's utilities to format and label the media.
The label on the media must meet the following restrictions:
Because the server opens only one file per physical removable medium, specify a capacity such that the one file makes full use of your media capacity.
For example, MAXCAPACITY=5M specifies that the maximum capacity for a volume in this device class is 5 megabytes. The smallest value allowed is 100KB (that is, MAXCAPACITY=100K).
