HP XP P9000 for Business Continuity Manager Software Reference Guide

NOTE:
• Do not execute the YKDELETE command during planned outage operation (when switching
the P-VOL and S-VOL). To dissolve the copy pair, switch the P-VOL and S-VOL again, return
the P-VOL to the primary site (restore normal operation), and then dissolve the copy pair.
• When operating the copy groups of a copy pair that was deleted with the DEVN parameter,
for the time that the copy pair is being synchronized, be sure to specify the SELECT(COND)
parameter.
• For EXCTG, if you execute the YKDELETE command and then the YKQUERY command to
obtain the copy pair status, the YKZ296E message sometimes appears when the dissolving
of the copy pair is detected at a different time from the dissolving of EXCTG, but this does not
mean that an error has occurred. For this reason (EXCTG), HP recommends that you execute
the YKDELETE command and then the YKEWAIT GOTO(SIMPLEX) command, wait until the
copy pair status changes to SIMPLEX, and then execute the YKQUERY command.
• In 4x4x4 Delta Resync configurations, when all copy pairs in EXCTG whose copy direction
is from the primary site to the remote site are dissolved, the journal groups whose copy direction
is from the local site to the remote site are also dissolved from EXCTG registration. For example,
if a Delta Resync is executed and then the YKDELETE
command is executed when EXCTG is in the HOLD status and the copy direction is from the
primary site to the remote site, the journal groups whose status is DUPLEX and copy direction
is from the local site to the remote site are dissolved from EXCTG registration. As a result, the
YKZ296E message is output if the YKQUERY command is executed to obtain the status of
Universal Replicator copy pairs whose copy direction is from the local site to the remote site.
In this case, perform either of the following operations to register journal groups in EXCTG
for the storage system:
◦ Execute the YKMAKE HOLDcommand for Universal Replicator copy pairs whose copy
direction is from the primary site to the remote site.
◦ Execute the YKMAKE command with a SELECT(COND) specified for Universal Replicator
copy pairs whose copy direction is from the local site to the remote site.
Return Codes
Table 102 (page 193) lists the return codes to be returned when the YKDELETE command terminates.
