Jump to solution

Hi All,

need your help to resolve the below issue.

I have created a SRDF pair two days back using a fresh rdf group.Today I have added few more devices to the same rdf group by mistake.I have to split the fisrt set of devices tomorrow morning as a part of server migration.

Currently the group is in adaptve copy mode and below are the query output.

2188 to 21DD is my first set nd which is going to migrate tomorrow.I tried to move the second pair of devices  to a new rdf group but the split/suspend command not working due to the invalid tracks.tried with force flag as well.

Since the group is in adpative copy mode,I want to know whether I can able to split the first set of devices alone today after shutting down the server.the devices will come to Synchronized mode.

can I split the first set if those devices are in Synchronized mode eventhough rest of devices are still syncing(group is in adaptive copy mode)

Yes you can.. put 2188 21DD in a text file and run symrdf -f <filename> split. You should be able to split one pair in this RA group as you are running ACP mode. If you are getting some error then please post your command and the error that you get.

You need to use the symforce option and edit the options file in /var/symapi/config/options--

# Parameter:                     SYMAPI_ALLOW_RDF_SYMFORCE

#

# Allowed Values:                TRUE | FALSE

#

# Component(s) Affected:         SRDF

#

# Default Value:                 FALSE
SYMAPI_ALLOW_RDF_SYMFORCE     = TRUE

Edit the SYMAPI_ALLOW_RDF_SYMFORCE  value to TRUE and issue a symforce command.

export the DG to a file and then delete the existing device group

symdg export testdg -file /tmp/testdg.txt

Edit the testdg.txt file and comment the devices which you dont wanna split.

Import the dg again

symdg import testdg -file /tmp/testdg.txt

then split it--

symrdf -g testdg split -rdfg XX -force -symforce -noprompt

Hi All,

I was able to split the required devices.I have created a DG for those devices.When we shut down the server the DG became synchronized and I was able to split it.

Thanks for all your comments.
