Monitoring journal (mirror) status
The status of a mirror associated with a journal relates to the pair operations that are performed
on the journal. Monitoring these statuses can help you resolve problems and maintain the Continuous
Access Journal system. Status for journals is viewed on the Journal Operation window.
Procedure 17 To view journal status
1. In Remote Web Console, click Actions > Remote Copy > Continuous Access Journal > Journal
Operation.
2. In the tree, open the Registered > LDKC00 child-tree, then select a journal. The group’s
information displays in the right-hand pane. See the Status column.
The mirror status for both Remote Web Console and RAID Manager appear together in the Status
column. However, the definitions are presented seperately in the following topics because there
is not a one-to-one relationship between them. Numerous RAID Manager mirror statuses can be
paired with Remote Web Console statuses. For mirror status definitions, see:
• “Remote Web Console mirror status definitions” (page 77)
• “RAID Manager mirror status definitions” (page 78)
Remote Web Console mirror status definitions
RAID Manager mirror statuses appear beside Remote Web Console statuses in the RWC/RAID
Manager format. The following describe Remote Web Console statuses.
