symclone commands

The symclone command performs various control operations on Device Group, Composite Groups and devices in these groups or the device in a pair file.

Below list contains some of the most useful symclone command examples.

• symclone -g TestDg activate DEV001 sym ld DEV002

  Activate the clone session.This will make the traget devices in ReadWrite(RW) mode.If the session created with a "-copy" option(default create option is copy), this will start the background copy from source to target device.There won't be any background copy if the session created with "-nocopy" option.

• symclone -g TestDg create DEV001 sym ld DEV002

  Create a clone copy session between the devices DEV001(source) and DEV002(target) in regular diskgroup TestDg. By default this will create a differentail session.That means, we can do a incremental recreate or restore later.This command will make the target device in Not Ready(NR).
  Copied

• symclone -g TestDg create DEV001 sym ld DEV002 -nocopy

  Create a "CopyOnAccess" clone session between the devices DEV001(source) and DEV002(target) in regular diskgroup TestDg.This wont start any background copying from source to target device even after activating the session.
  Copied

• symclone -g TestDg create DEV001 sym ld DEV002 -precopy

  Create a clone copy session between the devices DEV001(source) and DEV002(target) in regular diskgroup TestDg. This will start background copy from DEV001 to DEV002 after making the target device as NotReady(NR).
  Copied

• symclone -g TestDg recreate DEV001 sym ld DEV002

  Recreate a previously activated clone session.The session SHOULD NOT be created with a "-nocopy" or "-nondifferential" option.
  Copied

• symclone -g TestDg recreate DEV001 sym ld DEV002 -precopy

  Recreate a previously activated clone session.The session SHOULD NOT be created with a "-nocopy" or "-nondifferential" option.This will start an "incremental" background copy still keeping the target device in NR state.
  Copied

• symclone -g TestDg terminate DEV001 sym ld DEV002

  This will terminate the clone session between DEV001 and DEV002, deletes the pairing information from the storage array and removes any hold on target device.You have to 'Terminate' while the pair in 'Copied' state to get a fully valid data.
