Summary
This article provides suggestions for troubleshooting error return code 12110 (CM_ERR_UNK_ERRNO0).
Symptoms
DPX is generating a return code of 12110. The error is reported in the CMAGENT log which are those logs with an extension *.cml in the logs folder of DPX
Resolution
Make sure that all machines can resolve hostnames in accordance with the Backup Express readme file. You can modify the hosts file as part of the troubleshooting process. How many network interfaces are installed on the machine? Note the IP address of the enabled NIC or the NIC used to bind DPX communication. Edit the file "SSICMAPI":
- UNIX: /opt/DPX/misc/SSICMAPI
- Windows: Registry string value HKLM\Software\Syncsort\BackupExpress\<server name>\0\SSICMAPI
and append the following flag settings to the end, replacing information in [brackets]:
-hn [ipaddress of enabled NIC]
Note: For Oracle backups you will need to modify the file sbt11cfg.bex as well and change the SSICMAPI parameter.
If this is an Oracle RMAN backup, make sure that the node you specify in the value BEX_HOSTNAME_TO_BACKUP is the logical name of the node in the DPX database. This is not necessarily the hostname of the machine, replace this field with the logical name of the node within the DPX catalog.
