Selected Pairs table


Item	Description
Local Storage System	Information about volumes in the accessed system. LDEV ID: LDEV identifier. LDEV Name: LDEV name. Attribute: LDEV attribute. Capacity: Volume's capacity. CLPR: Volume's CLPR.
Copy Type	Type of pair: TC: TrueCopy
Status	Pair status.
Copy Priority	Order that pairs are resynchronized.
Remote Storage System	Information about the remote system. Model / Serial Number: Model and serial number. LDEV ID: LDEV identifier.
Path Group ID	Path group identifier.
CTG ID	Pair's consistency group identifier.
CTG Utilization	Whether the consistency group is shared by multiple pairs of primary and secondary systems. Single: The consistency group consists of a single pair of primary and secondary storage systems. Multi: The consistency group consists of multiple pairs of primary and secondary systems.
Copy Priority	Order that pairs are resynchronized.

Setting Fields


Primary Volume Fence Level	Whether the P-VOL can be written to when the pair is split due to error. Data: The P-VOL cannot be written to. Status: The P-VOL can be written to only if the primary storage system can change S-VOL status to PSUE; otherwise no. Never: The P-VOL can be written to. This is the default.
Copy Pace	Number of tracks to be copied per remote I/O during the operation. The default is 15. To change the copy pace, enter a number from 1 to 4: 1 is slow. This setting limits the impact on host I/O to maintain storage system performance. 2 and 3 is medium. 4 is fast. This setting increases the impact on host I/O and might result in decreased storage system performance. If you enter a number from 5 to 15, the speed of 4 (fast copy pace) is used.

Description

Primary Volume Fence Level

Whether the P-VOL can be written to when the pair is split due to error.

Status: The P-VOL can be written to only if the primary storage system can change S-VOL status to PSUE; otherwise no.

Copy Pace

Number of tracks to be copied per remote I/O during the operation. The default is 15. To change the copy pace, enter a number from 1 to 4:

1 is slow. This setting limits the impact on host I/O to maintain storage system performance.

4 is fast. This setting increases the impact on host I/O and might result in decreased storage system performance.

If you enter a number from 5 to 15, the speed of 4 (fast copy pace) is used.
