TrueCopy states

Normaly in a truecopy replication state we see different codes telling us teh health of the pairs. Here are the most common ones. Don't forget that P-VOL represents the primary volume (the one being replicated) and the S-VOL represents the secondary volume (the one replicating to).

TrueCopy states

Code State Details Replicating S-VOL state
SMPL simplex This volume is not part of any replications relationships. The host can access the volume No Read-Write
PAIR paired This volume has finished synchronization and it's in a relationship active. Active Read Only
COPY copying This volume is performing the initial copy operation. In progress Read Only
PSUS Pair Suspended-Split The volume is split NO but resumable N/A
SSUS Secondary Suspended-Split The S-VOL is accesible to the host for read or read/write operations NO but resumable R/W if pairsplit done with -rw
PSUE Pair suspend - error The pair is in a error state and not replicating NO but restartable (will start from 0% again) Read Only
PSUF Pair Full Sidefile Pair is split due to a sidefile full. NO but restartable (will start from 0% again) Read Only
PDUB ???? When using LUSE volumes this code tells you that one of the LDEVs within the LUSE has failed. NO but restartable (will start from 0% again) Read Only
SSWS Secondary suspended With Swap for failover. -

Here are the status states for paircreate/pairsplit and parresync
