Determines the name of the copy file system. If this flag is not provided, the
default naming convention applies. For example, the copy of the original file
system /data is named /fs/data.
Determines the name of the copy logical volume. If this flag is not provided,
the default naming convention applies. For example, the copy of the original
logical volume /lv001 is named /fslv001.
Provides information.
Calls the external trigger. You can use the external trigger when you want to
automate the copy process. In the automated script, run the ssa_make_copy
-v vgname -E external_file command. This command causes the script
ssa_make_copy script to wait until the file external_file has been created
before it flushes the cache and stops I/O. You have already determined how
long the copy operation takes to run. After that period, the file external_file is
created. If the file exists before the copy operation has completed the script,
an error is reported. The external trigger provides a good way to automatically
stopping I/O at the correct moment. If the -e flag is used, the default filename
applies: /tmp/ssa_copy_svs_trigger.
Uncouples the copy. This command is run only when you want to recreate the
copy volume group on another using system. When a copy array is uncoupled,
a new hdisk is created. This hdisk contains a copy of the data that was on the
parent when the copy was uncoupled.
Recreates a copy of the volume group on the copy disk drives.
v Changes PVID references of the VGDA to suit the PVIDs of the new hdisks.
v Renames the volume group and assigns a new VGID. Renames the logical
volumes.
v Changes the root mount point for all the file systems in the new volume
group.
v Mounts the file systems.
Prepares the volume group for a copy operation. This command does not
complete until the copy operations have completed.
Complete when copy ends. This flag can be used only with the -P flag. When
this flag is specified, the script waits for the copy operation to end.
