Continuous Access XP Journal split types (PSUS)

Table 5

describes Continuous Access XP Journal split types. You can split a Continuous Access XP Journal

pair at any time after the initial copy operation is complete. You must split a Continuous Access XP Journal

pair to perform media maintenance on the primary data volume or access the secondary data volume

(secondary data volume write enable).

PFUL

Continuous Access XP Journal monitors the total

amount of data in the journal volume. If the

amount of data exceeds the threshold (80%), the

pair status changes from COPY or PAIR to PFUL.

The write data that inflows is monitored during the

specified time (Data Overflow Watch). You can

use Command View XP or XP Remote Web

Console to set the monitoring time period (the

default is 60 seconds).

NOTE:

The PFUL status is displayed by RAID

Manager. Command View XP or XP Remote

Web Console displays this status as PAIR.
