@Sunil Thanks for your reply.
Actually our issue was complicated, so we opened a Commvault case “231205-249”.
Here you can find the case summary below:
-- SAP MAXDB backup using workflow is failing for client "xxxxx" - instance "xxx" with error 'Preparation of backup operation failed:Can not create pipe '\\.\pipe\pipe_mem1\.System error 13: Permission denied)
-- Client OS is SLES 15.4 and commvault installed is 11.28.83
-- OS user is "sqdxxx" , instance looks properly configured.
-- Noticed in client "id sqdxxx" , the groups are sdba and sapsys.
-- /opt/commvault/Base shows root:root as owner , we changed it to sapsys
-- Initiated workflow again and noticed error "File /SapMaxDbAgent/backint.conf is missing or unreadable
-- Connected to dbmcli and reviewd dbm_configget, looked correct yet we re-configured it as below:
=====
dbm_configset -raw BSI_ENV /opt/commvault/SapMaxDbAgent/backint.conf
dbm_configset -raw set_variable_0 LD_LIBRARY_PATH=/opt/commvault/Base
dbm_configset -raw set_variable_1 SHLIB_PATH=/opt/commvault/Base
=====
-- medium_getall looked incorrect, it included mem1, mem2, mem3, mem4 windows configuration as well.
Reference: https://documentation.commvault.com/v11/expert/configuring_multiple_streams_for_backups_and_restores.html
-- Once we corrected the medium pipes, initiated backup again and notice same error : "File /SapMaxDbAgent/backint.conf is missing or unreadable"
-- Further in /sapdb/xxx/backup/ saw the owner is sdba and not sapsys.
-- Did a cvpkg under /opt/commvault/Base and changed group owner from sapsys to sdba and initiated workflow again.
-- Backup workflow got completed now.
