PSUE types and behaviors

The primary system suspends a pair and changes its status to PSUE when it detects any of the
following:
The user has released the pair on the secondary system.
An error condition related to the secondary system, S-VOL, or an update operation.
The primary system is unable to communicate with the secondary system.
A Continuous Access Journal suspension condition is detected by the system.
The following describes the types of PSUE status.
PSUE Type
PSUE, S-VOL
Failure
PSUE, MCU IMPL
PSUE, Initial Copy
Failed
PSUE, MCU P/S

Description
Only the current pair was split or suspended.
Update sequence consistency between this S-VOL and other S-VOLs in the associated
journal is not insured.
This S-VOL cannot be used for disaster recovery at the secondary site.
This status is indicated when:
- The pair is split by the user using the Suspend Range-Volume (LU) pairsplit option.
- The pair is suspended due to a failure that did not affect the entire journal.
The pair was split or suspended along with the other pairs in the associated mirror.
Update sequence consistency between this S-VOL and other S-VOLs in this mirror is
insured.
This S-VOL can be used for disaster recovery on the secondary system.
This status is indicated when:
- The pair is split by specifying mirror of the pairsplit -r option.
- All pairs in the associated mirror are suspended due to a failure that affects the entire
group; for example, path failure.
- One pair in the mirror was suspended due to a failure that did not affect the entire
group.
Volume PSUE Type Description
Applies To
P-VOL, S-VOL The primary system detected an error during communication with the
secondary system or during update copying.
S-VOL PSUE type is usually PSUE-S-VOL Failure.
P-VOL, S-VOL The primary system could not find valid control information in its nonvolatile
memory during IMPL (Initial Microprocessor Mode). This condition occurs
if the primary system is without power for more than 48 hours (power
failure and fully discharged backup batteries).
P-VOL, S-VOL The pair was suspended before the initial copy operation was complete.
The data on the S-VOL is not identical to the data on the P-VOL.
S-VOL The primary system is powered off.
