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 81 and to
Table 26 on page 78.
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 81 lists the status displayed by the host for the SI390
and/or TC390 volume pair configurations.
• If the XP1024/XP128/XP12000/XP10000 contains only SI390 pairs, the CQUERY and PPRCOPY
QUERY commands will report the SI390 pair status.
• If the XP1024/XP128/XP12000/XP10000 contains only TC390 pairs, the CQUERY and PPRCOPY
QUERY commands will report the TC390 pair status.
