Pair status
Description
PFUL
If data in the journal volume exceeds 80%, pair status changes
to PFUL. The write data that inflows then is monitored during the
Data Overflow Watch.
PFUL status is displayed by RAID Manager. Remote Web Console
displays this status as PAIR.
PFUS
If the Data Overflow Watch period is exceeded, pair status
changes from PFUL to PFUS, and the pair is suspended.
The PFUS status is displayed by RAID Manager and Remote
Web Console as PSUS.
If a virtual volume of Thin Provisioning (V-VOL) is used as a
Cnt Ac-J S-VOL, and the capacity of a pool-VOL is nearly full,
Cnt Ac-J status becomes PFUS and the pair is suspended.
SSWS
After Takeover, SSWS is the status of the S-VOL. With this status,
data can be written to the S-VOL.
SSWS is displayed by RAID Manager, from which the
horctakover command is issued.
Remote Web Console displays this status as PSUS or PSUE.
*1: Accessing the P-VOL depends on the status of the Cnt Ac-S pair that shares the volume.
