SMS and ARCHIVE

Archive uses SMS Storage Group and Management Class information to determine the eligibility of a data set for archive.

The SMS fields that CA Disk supports are as follows:

Auto-migrate (SG) This required field can be defined YES, NO, INTERVAL or PRIMARY. When you define this field to YES, INTERVAL, or PRIMARY, CA Disk automatically allows archival. When you define this as NO, CA Disk does not allow archival of any of the data sets for the Storage Group.
GDG Elements on Primary (MC) This optional field can be defined 0 to 255 or blank. The default is blank. When this field is defined with a number, it indicates the maximum number of most recent generations of a GDG on primary. If there are more GDGs than the maximum, the extra ones are archived. If there are fewer than the maximum, none are archived. When this field is defined with a blank, other Management Class attributes will be used to process the data set.
Rolled-off GDS Action (MC) This optional field can be defined MIGRATE, EXPIRE, or blank. The default is blank. When this field is defined MIGRATE, CA Disk makes the data set eligible to archive unless the expire attributes in the Management Class indicates that the data set should be expired in which case the data set will be deleted. When this field is defined EXPIRE, CA Disk deletes the rolled-off data set unless the explicit expiration date in the format-1 DSCB is not met. When this field is defined with a blank, CA Disk makes the data set not eligible to archive and will expire the data set based on the Management Class attributes.
Primary Days Non-usage (MC) This optional field can be defined 0 to 9999 or blank. The default is 60. When this field is defined with a number, those number of days must pass since the last used date before the data set is eligible for archive. When this field is defined with a blank, other Management Class attributes will be used to process the data set.
Level 1 Days Non-usage (MC) This optional field can be defined 0 to 9999, NOLIMIT, or blank. The default is 60.
Note: When this field is defined 0 and archive to disk is being performed, data sets with this attribute are bypassed.
Command or Auto-migrate (MC) This optional field can be defined BOTH, COMMAND, or NONE. The default is BOTH. When this field is defined BOTH, CA Disk can archive the data set both implicitly and explicitly. When this field is defined COMMAND, CA Disk can archive the data set only explicitly. When this field is defined NONE, CA Disk cannot archive the data set.

This example:

SCAN REALVOLS

SELECT SGNAME=/

ARCHIVE

accomplishes the following:

Select the volumes contained in all Storage Groups.
Select the data sets meeting the appropriate Management Class and Storage Group attributes.
Archive the data sets.
