Hi @Nikos.Kyrm 

Appears to be a permissions issue. Can you review if the installation is done with right user and groups?

After you complete the installation,

• Review the required permissions. For more information, see Database Group and Folder Permissions.

• Change permissions as needed. For more information, see Changing UNIX Groups and Permissions on UNIX Clients.

• Perform the configuration procedures. For more information, see SAP MaxDB Configuration.

Thanks,

Sunil

@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.

Best regards,
Nikos

what do you need to configure from linux and what you need to configure thru dbcli?

Hello @Edvinas Jack ,

I’m not sure. In my case, most of the configuration in Linux done from Sap admin in collaboration with Commvault support.
