•
Pair resynchronization command: Resynchronizes a split volume pair based on the primary
volume. The primary volume remains accessible during resynchronization.
◦ Swaps(p) option (Continuous Access Synchronous only). Swaps volume from the
S-VOL(P-VOL) to the P-VOL(S-VOL) when the S-VOL(P-VOL) is in the suspended state and
resynchronizes the NEW_S-VOL based on the NEW_P-VOL. At the result of this operation,
the volume attributes of the host of reference (local host) are used as the attributes for the
NEW_P-VOL(S-VOL).
•
Event waiting command: Used to wait for the completion of volume pair creation or
resynchronization and to check the pair status.
•
Pair status display and configuration confirmation command: Displays the pair status and
configuration of the volume pairs and is used for checking the completion of pair creation or
pair resynchronization.
Figure 52 Continuous Access Synchronous remote system configuration
Continuous Access Synchronous local commands
Figure 53 (page 128) illustrates a Continuous Access Synchronous local configuration. The RAID
Manager Continuous Access Synchronous local commands assist the system operation with volume
backups among UNIX servers and their operating system management functions. The Continuous
Access Synchronous local commands perform the same functions as the remote commands but
within the same RAID storage system instead of between two RAID storage systems.
