7 Monitoring the system
Monitoring pairs, journals, data paths, I/O, and hardware performance is crucial for ensuring
that Continuous Access Journal pairs continue to function correctly.
This topic provides information and instructions for monitoring a Continuous Access Journal system.
Monitoring pair activity and status
Monitoring the Continuous Access Journal system is essential for maintaining your pairs.
•
Each operation requires a specific status or statuses. Before performing a pair operation,
check the pair’s status.
•
Pair status changes when an operation is performed. Check status to make sure that pairs are
operating correctly and that data is updated from P-VOLs to S-VOLs, and that differential data
is managed appropriately.
Frequent monitoring of the system is optional but recommended. You can set up automatic e-mail
notification from the RWC for problems found during monitoring (see the HP XP P9000 Remote
Web Console User Guide).
Procedure 14 To monitor pair activity
1. In the Remote Web Console main window, click Actions > Remote Copy > Continuous Access
Journal > Pair Operation.
2. In the Pair Operation window, locate the pair whose status you want to review and check its
status in the Status column.
3. To filter the list, click Display Filter. Headings are described in “Display Filter dialog box ”
(page 174) and the Help.
4. To export pair information, see “Saving pair information to a text file ” (page 72) .
5. To view more detailed pair information, right click a pair and then select Pair Status from the
menu.
Pair status definitions
Both Remote Web Console and RAID Manager pair status names appear in the Remote Web
Console Status columns, except when the names are the same. When they are the same, the RAID
Manager status does not appear.
The following table shows both types of status names and their descriptions. In some cases, a
particular status has no exact parallel status in the other interface. This is noted.
When checking your pairs’ status, click File/Refresh to make sure the data is current.

Read/Write Read/Write The volume is not assigned to a pair and is not in a journal. SMPL SMPL
•
When the volume is added to a pair, the status changes
to COPY.
•
When a pair is deleted, the volumes’ status changes back
to SMPL.
If a pair is deleted from the secondary system, S-VOL
status changes to SMPL; when the primary system detects
this, P-VOL status changes to PSUS. The pair must be
deleted from the primary system also to change P-VOL
status to SMPL.
