When migrating the MIMIX for AIX Host System to new hardware, the
HOST_ID of the system changes. As MIMIX for AIX depends on this
HOST_ID, it will stop functioning until the
HOST_ID is updated in the MIMIX ODM. The procedure below explains
how to automate this update process to maintain uninterrupted operation.
The /usr/scrt/bin/es_hostid_update command is used to update the
HOST_ID in the MIMIX ODM for both Primary and Failover Context
IDs.
Syntax:
/usr/scrt/bin/es_hostid_update -C <Primary Context ID> -T <production/backup> -H <HOST_ID>
- -C <Primary Context ID>: Specifies the Primary Context ID.
- -T <production/backup>: Identifies the environment where the change is required (production or backup).
- -H <HOST_ID>: Specifies the new
HOST_ID. - -h: Displays help information for the command.
Example,
# /usr/scrt/bin/es_hostid_update -C 1 -T backup -H 621DE751CE
Provided Primary Context-ID=1
Server/Environment, where change is required=backup
Host-ID which is required to be changed to=621DE751CE
Failover Context-ID found for the Primary-Context(1)=11
DO YOU CONFIRM?
Answer in Yes or yes or y or No or no or n
yes
answer is yes
Current HOST_ID for the Primary-Context="621DE751DA"
Current HOST_ID for the Failover-Context="621DE751DA"
Changing to the provided HOST_ID for the Primary_Context....
