Security Group List

Description

Indicates the selected LDKC number.

Descriptive information about the security groups in the LDKC.

•Security indicates whether the security settings in the security group are Enabled or Disabled.

CAUTION:

It is possible that security settings are disabled even if Enabled is displayed. If the Status is Access and the security group contains neither a host nor an LDEV group, security settings in the security group are disabled unconditionally.

•Group Status indicates whether the security group is an Access or a Pool group. If Access appears, the security group is an access group; volumes in the group can be accessed only by hosts registered in the same group. If Pool appears, the security group is a pool group; volumes in the group cannot be accessed by any hosts.

•T-VOL/R-VOL indicates whether volumes in the security group can be used as secondary volumes (i.e., copy destination volume). Enable indicates the volumes can be used as second- ary volumes. Disable indicates the volumes cannot be used as secondary volumes.

NOTE:

Secondary volumes (that is, copy destination volumes) are often referred to as remote volumes or R-VOLs in the Hitachi TrueCopy™ for Mainframe User's Guide. Also, secondary volumes are referred to as target volumes or T-VOLs in the Hitachi ShadowImage™ for Mainframe User's Guide.
