NOTE:

If an SI390 pair is suspended because of an internal disk array error condition, the QUIESCE

option is applied. In this case, release the QUIESCE condition by deleting the pair.

SI390 and TC390 are processed independently. The CSUSPEND/QUIESCE command is effective for

either the SI390 or TC390 pair specified in the command.

Resynchronizing Pairs: MODE(RESYNC) Parameter

The MODE(RESYNC) option of the CESTPAIR and PPRCOPY ESTPAIR commands is equivalent to the SI390

normal resync operation (changes pair status to resync). The following are examples of the CESTPAIR

command with the MODE(RESYNC) parameter and the PPRCOPY ESTPAIR command with the

MODE(RESYNC) parameter. These commands must be issued to the S-VOL and the pair status must be split

or suspend when MODE(RESYNC) is specified.
Example: CESTPAIR with MODE(RESYNC) Parameter

Example: PPRCOPY ESTPAIR with MODE(RESYNC) Parameter

Deleting Pairs: CDELPAIR and PPRCOPY DELPAIR

The CDELPAIR and PPRCOPY DELPAIR commands are equivalent to the SI390 delete pair operation

(changes pair status to simplex). The following are examples of the CDELPAIR and PPRCOPY DELPAIR

commands. These commands must be issued to the S-VOL.
A DELPAIR command performed when pair status is split enables the T-VOL to be accessed by the host. A

DELPAIR command performed when pair status is other than split allows non-reserved T-VOLs to be

accessed by the host. Reserved simplex volumes cannot be accessed.

CAUTION:

For duplex SI390 pairs, the S-VOL and its associated T-VOL(s) are usually not identical

because SI390 update copy operations are asynchronous. Therefore, if a pair is deleted with status other

than split, the data integrity of the T-VOL cannot be guaranteed.
