0m, and recovered from a different device file, such as /dev/rmt/2m, even though the physical
device is the same.
Question:
How can I recover a system which has volume groups configured using Cluster-wide Device Special
Files (cDSF)?
Ignite-UX supports cluster-wide Device Special Files (cDSF) from the C.7.16.x release. No extra
steps need to be performed during the creation of an archive or during the recovery process. If a
volume group is configured with cDSFs during the creation of an archive, it is recovered with the
cDSFs..
IMPORTANT: During a recovery, the consistency of cDSFs is not checked across the systems
sharing the storage. As a recovery archive is from a previous point in time and changes to the
cDSFs visible to a system may have occurred, you must ensure that the volume group contains the
correct cDSFs before you attempt to use it. Failing to do so may cause data corruption and/or an
extended system or application outage. Please consult the io_cdsf_config(1m) manual page for
information on how to view, diagnose and correct potential conflicts with cDSFs.
