ShadowImage for the XP128/XP1024/XP10000/XP12000

NOTE:

PPRIMARY and PSECONDRY indicate that the volume is in the DUPLEX state.

Adding Pairs: CESTPAIR and PPRCOPY ESTPAIR

The CESTPAIR and PPRCOPY ESTPAIR commands are equivalent to the SI390 add pair operation (changes

pair status to pending). The following are examples of the CESTPAIR and PPRCOPY ESTPAIR commands.

These commands must be issued to the S-VOL of the pair being created and the T-VOL must be offline to

the host before these commands are issued.
Example: CESTPAIR Command

Example: PPRCOPY ESTPAIR Command

Displaying Pair Status: CQUERY, PPRCOPY QUERY, DEVSERV

The CQUERY TSO and PPRCOPY QUERY ICKDSF commands are equivalent to the SI390 pair status

display and status and history functions. The following are examples of the CQUERY and PPRCOPY

QUERY commands.
The DEVSERV command can also be used to display SI390 pair status. For a description of the DEVSERV

command results for SI390 volumes, refer to the example of the DEVSERV command on page 78 and to

Table 26

on page 75.

SI390 supports multiple T-VOLs for an S-VOL, and SI390 and TC390 can both be defined for the same

volume. When multiple pairs exist on one volume, the CQUERY and PPRCOPY QUERY commands can

only report the status of one pair.

Table 27

on page 78 lists the status displayed by the host for the SI390

and/or TC390 volume pair configurations.

If the XP128/XP1024/XP10000/XP12000 contains only SI390 pairs, the CQUERY and PPRCOPY

QUERY commands will report the SI390 pair status.

If the XP128/XP1024/XP10000/XP12000 contains only TC390 pairs, the CQUERY and PPRCOPY

QUERY commands will report the TC390 pair status.
