Hi Shahid,
Please replace '-u' in SDBAC table with '-u //'. I guess more or less actual kernel disk was used to upgrade the SAP System. Because of this, OPS$ connect mechanism (with -u /) is no longer supported. Specify -u // in the command line as below to check if SSFS is/was configured and working with BR*Tools:
brconnect -u // -f dbstate
Regards,
János
