Table 29 Continuous Access Journal pair status
Secondary Primary Continuous Access Journal Pair Status Status
R/W enabled R/W enabled Unpaired volume SMPL
R enabled R/W enabled The pair is synchronized. Updates to the P-VOL are duplicated on
the S-VOL. PAIR
R enabled R/W enabled In paired state, but initial copy, pairsplit, or resync operation is not
complete. Includes COPY(PD), COPY(SP), and COPY(RS) status. COPY
R/W enabled when
using write enable
pairsplit option R/W enabled The user has split the pair or released the pair; the pair is no longer
synchronized. PSUS
(split)
SSUS
(split) • The primary and secondary systems keep track of journal data
discarded during the pairsplit operation.
•
When the operation is performed at the primary system, the status
of both the P-VOL and S-VOL changes to PSUS.
• When the operation is performed at the secondary system, the
status of the S-VOL changes to PSUS; the primary system detects
this (if path status is normal) and changes P-VOL status to PSUS.
•
When a pair is released from the secondary system, the secondary
system changes the status of the S-VOL to SMPL. The primary
system detects this (if path status is normal and changes P-VOL
status to PSUS. (The pair must be released from the primary system
to change P-VOL status to SMPL.)
R enabled R/W enabled if no
error occurs in the
primary volume The pair is suspended due to an error; the pair is not synchronized. PSUE
•
The primary and secondary systems keep track of any journal
data that are discarded during the suspension operation.
• The primary system keeps track of P-VOL tracks that are updated
while the pair is suspended.
•
When a Cnt Ac-J suspension condition is detected, the primary
system changes P-VOL and S-VOL status to PSUE. If the secondary
system detects the condition, it changes the S-VOL status to PSUE;
the primary system detects this and changes P-VOL status to PSUS.
Read Only, unless write
option is enabled. R/W enabled If the Data Overflow Watch period is exceeded, pair status changes
from PFUL to PFUS, and the pair is suspended. PFUS
• The PFUS status is displayed by RAID Manager and Remote Web
Console as PSUS.
•
If a virtual volume of Thin Provisioning (THP-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.
R/W enabled R enabled After Takeover, SSWS is the status of the S-VOL. With this status,
data can be written to the S-VOL. SSWS
• SSWS is displayed by RAID Manager, from which the
horctakeover command is issued.
•
Remote Web Console displays this status as PSUS or PSUE.
R enabled R/W enabled If data in the journal volume exceeds 80-percent, pair status changes
to PFUL. The write data that inflows then is monitored during the Data
Overflow Watch. PFUL
PFUL status is displayed by RAID Manager. Remote Web Console
displays this status as PAIR.
