Setting an HA Group Member to Standby

Some HA group members can be designated as standby members. Standby members do not perform any cryptographic operations unless all active members have failed (see Standby Members for details). They are useful as a last resort against loss of application service.

Prerequisites

The partition you want to designate as a standby member must already be a member of the HA group (see Adding/Removing an HA Group Member). The Crypto Officer must perform this procedure.

To set an HA group member to standby

1.[Optional] Check the serial number of the member you wish to set to standby mode.

lunacm:> hagroup listgroups

2.Set the desired member to standby mode by specifying the serial number (see ).

lunacm:> hagroup addstandby -group <label> -serialnumber <member_serialnum>

lunacm:> hagroup addstandby -group myHAgroup -serialnumber 2855496365544

        The member 2855496365544 was successfully added to the standby list for the HA Group myHAgroup.
