Hitachi MP-96RD625-01 manual Hitachi Universal Replicator for IBM /OS User’s Guide

Note: If you selected more than one primary data volume, select the secondary data volume for the primary data volume being displayed. The secondary data volumes for the rest of the primary data volumes are automatically assigned according to the volume number. For example, if you select three primary data volumes and select 01 as the S-VOL for the first primary data volume, the secondary data volumes for the two other primary data volumes will be 02 and 03.

Note: When creating more than one pair at a time, make sure that the S- VOLs to be assigned automatically are available. If an S-VOL is not available, you will have to select the S-VOL individually.

•Select Other S-VOL(s): Specify how URz automatically will assign secondary data volumes if two or more primary data volumes are selected in the Pair Operation window.

–Increment: URz increments volume numbers of the resulting secondary data volumes one by one. For example, if the volume numbers of the three primary data volumes are 01, 02, and 03, the volume numbers of the resulting secondary data volumes will be 11, 12, and 13 if you select the volume number 11 with the S-VOLdrop-down list.

–Input Next: URz users can specify a volume number for each primary data volume. For example, if two primary data volumes are selected, the URz user must select Input Next, specify the secondary data volume for the first primary data volume with S-VOL, and then click Set. Next, the user must specify the secondary data volume for the second primary data volume with S-VOL, and then click Set.

–Relative to P-VOL: URz calculates the difference between volume numbers of two adjacent primary data volumes, and then determines volume numbers of secondary data volumes.

For example, if the volume numbers of the three primary data volumes are 01, 05, and 06, the volume numbers of the resulting secondary data volumes will be 02, 06, and 07 if you select the volume number 02 with the S-VOLdrop-down list.

Note: If you select and right-click more than one volume in the Preview list and then select Modify, the Add Pair window appears and the Select Other S-VOL(s)drop-down list displays No Change. If you want to change the setting with this drop-down list, select another item from the drop-down list.

•Mirror: Assigns a master journal group to the primary data volume, assigns a restore journal group to the secondary data volume, and also assigns a mirror ID to the volume pair.

–M-JNL: Assigns a master journal group to the primary data volume.

Note: M-JNLdoes not display journal group numbers used by Universal Replicator.

–Mirror ID: Assigns a mirror ID to the volume pair.

–R-JNL: Assigns a restore journal group to the secondary data volume.
