I replied to this on the Yahoo storage board, and wanted to share it.
Â Excepting in the case of Dynamic SRDF, the pairings are fixed, having been set by EMC when the CE installs the binfile.Â These relationships are more or less hard-coded into the Symmetrix and can’t be changed without breaking the pairs and re-establishing them, whether through the command line (symconfigure) or a new binfile request from EMC.
As far as the device pairings in Timefinder, these pairings are first created in the device group for use with the -g switch (or in a device map file for use with the -f switch).Â Once these pairings are made, they are the “default” pairing for each device.Â (IE if you issue a general establish or split on a group, the devices will always pair up the same way.)Â The only way to break that is to do an establish with a different map file (or device group) usig the -force -full.
As always, I counsel against using -force or -symforce on anything, as it usually means you’re telling the Symm to do something it’s not going to like.
