Troubleshooting
Because there are several device naming schemes possible when using dm-multipath devices (see the
section titled “Device naming” above), it may be necessary to create a custom version of the device_info
file that is used as a reference for device naming schemes. If the restore fails because your partitions are
not discovered during install, reboot from the boot media and customize the /opt/storix/config/device_info
file.
Here are the steps to customize the /opt/storix/config/device_info file from the boot media:
1) Power cycle the system.
2) From the System Installation and Maintenance Main Menu, select System Recovery Utilities,
select Start a Maintenance Shell to access a terminal. The vi editor is available for making
changes to the /opt/storix/config/device_info file.
3) Update the device_info file to match the naming scheme for your environment. Again, for
information on dm-multipath device names, see the section titled “Device naming” previously
referenced in this document.
4) Copy
the updated device_info file to the local SBAdmin data directory. The path is already stored
in the variable $STXPATH. You can reference that path in the maintenance shell.
# mkdir $STXPATH/config
# cp /opt/storix/config/device_info $STXPATH/config/device_info
The custom version of device_info will be copied to the restored system for further use.
Restoring a system using dm-multipath devices
Restoring a system using dm-multipath devices is the same as restoring a normal Linux system. For further
detail please refer to the
SBAdmin Linux System Recovery Guide .
