RDF System Management Manual for H-Series RVUs (RDF 1.8)

RDFCOM INFO and SHOW Commands
The INFO command output includes the RDF and extractor configuration attributes for ZLT, as
does the output for the SHOW command.
Old Audit-Trail Files
When a ZLT takeover operation completes, you should not purge the old audit-trail files on the
remote mirrors connected to the standby system if you believe you can recover the primary
system. The old audit-trail files are necessary for recovering the primary system.
If you can’t recover the primary system, you might purge the files because they have no further
use.
Because the old audit-trail files are not managed by TMF on the standby system, if you choose
to purge them you must do so manually using Snoop.
Recovering the Primary System After an RDF ZLT Takeover
If you had to execute the RDF takeover operation and you are able to bring your former primary
system back online, you must perform these tasks to recover the database on your former primary
system.
