Device does not have any BCV pairing relationship while ESTABLISHing

I had created a STD and a BCV device and associated them, Now when I try to ESTABLISH them, I get an error saying - 
C:\>SYMMIR -G SCCL202PDT establish
 
Execute 'Incremental Establish' operation for device group
'SCCL202PDT' (y/) ? y
 
'Incremental Establish' operation execution is in progress for
device group 'SCCL202PDT'. Please wait...
 
 
Cannot proceed because the device does not have any BCV pairing relationship
 


The following procedure was followed:

Create a DG:

symdeg create SCCL202PDT -type REGULAR

Added a std device to disk group:

symld -g SCCL202PDT add dev 1EBD -sid xxx

Associate the BCV :

symbcv -g SCCL202PDT associate 1EC4 -sid xxx




C:\>symdg show SCCL202PDT

What is that I am missing that is causing not to establish ?

Thanks!

Cannot proceed because the device does not have any
BCV pairing relationship


When you issue "symmir establish" it will default to an incremental establish. But an incremental establish requires a previous full establish. The default behaviour of S.E. is to report an issue (the one you are experiencing).

You can either

1) issue a "symmir -full establish"
2) change "options" file and enable automatic full establish when no previous one exists

Cheers :-)

Thanks Stefano!!!! You rock \m/ :-)

I didnt understand the 'options' you mentioned

You can find "options" file in /var/symapi/config or X:\Program Files\EMC\symapi\config ...
It offers a lot of tweaks on Solution Enabler behaviour.
One of the tweaks is the following:

#
# Parameter:                         SYMAPI_BCV_ESTAB_INC_TO_FULL
#
# Allowed Values:                    ENABLE:  Will cause an incremental BCV  
#                                             establish to automatically be 
#                                             converted to a full establish if
#                                             needed.
#                                    DISABLE: As in prior revisions, will not
#                                             cause incremental establishes to
#                                             be converted to full establishes.
#
# Component(s) Affected:             TimeFinder
#
# Default Value:                     DISABLE
