Failover
1. From the local site, execute the YKSUSPND REVERSE command for the Cnt Ac-S Z copy pair.
• YKQUERY
• YKSUSPND REVERSE
• YKEWAIT GOTO(SUSPEND) NOINVALIDCHECK
If a route list that contains the primary site is specified for the YKLOAD command, the YKQUERY
command and the YKEWAIT command may sometimes encounter an I/O error. To avoid an
I/O error, specify a route list that does not contain the primary site.
Operation at the local site can be started before executing the YKRESYNC DELTAJNL
command. However, the time it takes for the delta resync pairs between the local site and the
remote site to change to the DUPLEX status after execution of the YKRESYNC DELTAJNL
command increases depending on the amount of update data from the local site.
2. From the local site, execute the YKRESYNC DELTAJNL command for the delta resync pair.
• YKQUERY
• YKRESYNC DELTAJNL
• YKEWAIT GOTO(DUPLEX)
