Using the Group Display Panel

By selecting option 1 from the Main Menu, information about the CA Vtape Externalization groups is displayed. These groups control whether Virtual Volumes are compressed when written to the DASD buffer and how they are Externalized to physical tape.

The following panel will be displayed:

The information shown includes the following:

Max Drives

Maximum number of drives that the Backstore Engine can use concurrently.

In Use

Number of drives currently in use.

MAX USS

Maximum number of UNIX files that the Backstore Engine can use concurrently.

In Use

Number of UNIX files currently in use.

Grp ID#

Group number.

WQ

Whether or not work is presently queued for Externalization.

Loc Rmt

Indicates whether the Group is defined for local or remote (P2P) use.

Vol Pool#

Shows the assigned Volume Pool definition for the Group.

Comp Opt

Displays the HardwareCompressionOption parmlib attribute setting. Options are as follows:

Y

Yes (compression is active).

N

No (compression is not active).

JCL

The TRTCH parameter in your JCL or the default drive setting determines whether compression is used (compression is optional).

Primary

Device type or esoteric to use when creating a primary tape.

Duplex

Device type or esoteric to use when creating a duplex tape.

Exp/Tri

Device type or esoteric to use when creating the Export tape or USS when creating a Triplex copy.

Sub Group

Groups are broken down into three subgroups based on the ShortRetention, MediumRetention, CatalogControlSubgroup, NeverExpireSubgroup, and SpecialRetention parmilb attributes. The values for the ShortRetention and MediumRetention attributes are displayed. Options are as follows:

Short

Expiration dates less than or equal to this number of days.

Medium

Expiration dates greater than the Short number of days and less than or equal to this number of days.

Long

Expiration dates greater than the Medium number of days.

You can issue the following line commands in this panel:

D

Shows another panel listing the parmlib attributes defined for the selected Group.

Q

Shows another panel listing the Virtual Volumes waiting to be Externalized in the subgroup queues for this group.

S

Shows another panel listing the partially full Backstore Tapes used for this group that Externalization will remount for filling.
