Hello,

We have two AIX5.3s with a HACMP active-standby environment that connected to a Tagmastore USP in a TrueCopy-synchronous primary site, and a AIX5.3 that connected to a Tagmastore USP in a TrueCopy-synchronous secondary site. We will setting up of the TrueCopy-synchronous (fence level which set to DATA) enviroment to a disaster-recovery automation, but we have no idea in some case...

We have some question below.
Item 1) In primary site failure, when two AIX5.3s goes to dead, how to swap-takeover automatically?
Item 2) In primary site failure, when the Tagmastore USP goes to dead, how to svol-takeover automatically?
Item 3) In secondary site failure, when the Tagmastore USP goes to dead, how to pvol-takeover automatically?
Item 4) In network failure between the primary site and the secondary site, when the network goes to dead, how to pvol-takeover automatically?

Best Regards,
Masahiko
