Planned outage of both primary and secondary systems
When you plan an outage of the TrueCopy primary and secondary systems at
the same time, the primary system must be powered off first and then
powered on last.
To perform a planned outage of the primary and secondary systems
1. Perform the planned outage of the primary system first. Because a
planned outage does not affect pairs, nothing out of the ordinary must be
done regarding the TC system or operations.
2. If a secondary system to be powered off is connected to a primary system
that is not powered off, split the pairs before powering off the secondary
system. Confirm that the pair status changes.
3. Perform the planned outage of the secondary systems as described in
Planned outage of the secondary system or remote path on page 7-20.
4. Power on the secondary systems. Make sure that they are fully
operational and ready to resynchronize operations before powering on the
primary system.
5. Power on the primary system, and make sure it is ready to resynchronize
operations. If you split any pairs in step 2, you can also resynchronize
those pairs now.
