symmir is specific to the BCV relationship - not the srdf pairing.  Just to verify,  here is the setup for the first lun:  DEV:       0385 BCV R1:  05d0 R2:          0134  Is that right? Which relationship are you trying to break,  the BCV -> R2 SRDF pairing or the R1 -> BCV pairing?  If you want to break the RDF pairing between 05d0 and 0134 you should be able to do this:  symrdf -sid 1033 -f devicemap.cfg -rdfg 4 split -force  Where device map.cfg " " is:  05d0 0134  That will force srdf it into split mode.  You aren't using dynamic srdf,  so you need to use symconfigure to convert the device to the mode you want.  If you want it to be just an BCV (maintain the relationship between 0385 and 05d0) you need to make a test config file as such:  convert dev 05d0 to BCV+R5  If you want to destroy the relationship between 0385 and 05d0 as well,  you create you config file like this:  convert dev 05d0 to 2-way-mir  Then to run your symconfigure, start with a preview:  symconfigure -sid 1033 -f configfileyoujustmade.text preview  If it works do a prepare / commit and you should be good to go - but keep in mind all data on the BCV and R2 will be lost, so make sure you really want to do this.
I have a device group that is no longer need. I removed all the devices from the device group and deleted the device group.  I unmasked and unmapped all the devices that were in the device group (Standard volumes and R1-BCV's).  Now I want to dissolve the R1/R2 relationship so I can reuse these volumes as standard RAID+5 volumes. The R1-BCV volumes need to be converted to Standare RAID+5 volumes.  What is the correct procedure to accomplish this? This is what I have tried:  symrdf -file aaa -sid 1033 -RDFG 4 deletepair -force  Where aaa consistes of the local R1-BCV and the remote R2-STD in the form of 05cf 0133 This worked fine.  Then when I tried to convert the R1-BCV to a STD RAID+5 through Control Center, it would give me an error:  SYMAPI Error - SYMAPI_C_CFG_COMMIT_FAILED SYMAPI_C_SRVR_INVALID_CONFIG Configuration Server Error Num - 0x8703 Configuration Server Error - The state of a snap session is blocking the activation of the new configuration. Please see the API log file Check the SYMAPI Log for more details and call EMC Customer Support  I called customer support and they told me to cancel the session using the following command:  symmir -sid 1033 -f bbb cancel  Where bbb consist of the R2-STD R1-BCV in the form of 0133 05cf  This worked on the first volume of the device group so I tried it again on another volume from the old device group.  I did the same steps and when I did the symmir -sid 1033 -f bbb cancel with the new R2-STD R1-BCV in the file bbb consisted on 0134 05d0 it gave me this error:  Cannot operate on the device because it is a 'META MEMBER'  This device is not a META device. I have tried several other devices using this procedure and get the same error.  Am I not using the proper procedure to delete the R1/R2 relationship in order to convert the R1-BCV to a STD
