The following table shows both types of status names and their descriptions. In some cases, a particular status has no exact parallel status in the other interface. This is noted.
The P-VOL access and S-VOL access columns in the following table indicate whether the volumes accept read/write.

Description |
P-VOL access |

|---|---|---|---|

SMPL |
This volume is not currently assigned to a TrueCopy pair. |
Read/Write |
Read/Write |
|
COPY |
The initial copy operation for this pair is in progress. This pair is not yet synchronized. |
Read/Write |
Read Only |
|
PAIR |
The initial copy operation is completed and the TrueCopy pair is synchronized. |

PSUS |
CCI PSUS status indicates that although the paired status is retained, the user split the pair and update to the S-VOL is stopped. This status is only for the P-VOL. While the pair is split, the storage system keeps track of updates to the P-VOL in the differential bitmaps. |
Read/Write |
- |
|
SSUS |
CCI SSUS status indicates that although the paired status is retained, the user split the pair and update to the S-VOL is stopped. This status is only for the S-VOL. If the option for permitting updates to the S-VOL is specified when the pair is split, the storage system keeps track of updates to the S-VOL in the differential bitmaps. |
- |
Read Only if Secondary Volume Write option is disabled. Read/Write if Secondary Volume Write option is enabled. |
|
PSUE |
CCI PSUE indicates that although the paired status is retained, updates to the S-VOL is sopped due to an error status. CCI PSUE is PSUS (SSUS) caused by an internal error. |
Read/Write. Read only if the fence level is Secondary Volume Data. |
Read Only |
|
SSWS |
CCI SSWS status indicates that the pair status is retained. The P-VOL and the S-VOL of the pair is switched and then they are resynchronized (horctakeover). | - | Read/Write |
