d. Remove virtual tapes from the newly created VTLs, if VTLs were created. These
virtual tapes are created automatically but cannot be used to store data that is
exported by the remote export jobs. Refer to the online help for instructions.
e. Recreate and schedule all of Server A’s jobs on Server B, including the remote export
jobs (whose target should be Server A). Be sure to disable these jobs; they should not
run until after the roles of the servers have been swapped. Refer to the online help for
instructions.
f. If Data Encryption is licensed, it is recommended that you configure Server B to use
Server A as its key generator.
4. To swap roles:
a. If Server A is available:
Stop all backup operations to Server A.
Disable all jobs on Server A, including the remote export jobs that export data to
Server B. See the “Modifying a job” help topic in the online help.
Remove virtual tapes from all VTLs on Server A, if VTLs are used. See the
“Removing a virtual tape from a VTL” help topic for details.
b. Load virtual tapes that were exported from Server A into VTLs on Server B, if VTLs
are used. These virtual tapes are needed by the host servers, to back up data on
Server B. See the “Adding a virtual tape to a VTL” help topic for details.
c. Enable jobs on Server B.
d. If Data Encryption is used in the environment and Server A was the key generator,
you do not need to perform additional steps to continue to use Data Encryption after
swapping roles. However, if Server A is not available, you can restore a backup of
Server A’s key database from a remote host. Then, you can configure Server B to be
the key generator. See the Managing Data Encryption help topics in the online help
for details.
e. Back up data from host servers to Server B as needed.
At this point, Server B has become the primary server.
To restore roles
1. Cease production on Server B:
Stop all backup operations to Server B.
Disable all jobs on Server B, including the remote export jobs that export data to
Server A. See the “Modifying a job” help topic in the online help.
Remove virtual tapes from all VTLs on Server B. See the “Removing a virtual tape
from a VTL” help topic for details.
2. Load virtual tapes that were exported from Server B in VTLs on Server A. These virtual
tapes are needed by the host servers, to back up data on Server A. See the “Adding a
virtual tape to a VTL” help topic for details.
3. Enable jobs on Server A.
4. Back up data from host servers to Server A as needed.
