Linux Hybrid version of the plug-in does not run on 64-bit OS
The Linux Hybrid version of the plug-in does not run on pure 64‑bit operating system.
The plug-in fails to open and displays the message “No Error.”
Pure 64-bit operating systems do not install some common 32-bit libraries the plug-in requires.
To correct this problem, do the following:
|
NOTE: Some libraries are dynamically loaded from the path $NV_HOME/dynlib/vddk/. If these libraries are listed as missing, no action is required. |
Crash occurs during a backup
During a backup, the plug-in reports an error and stops responding.
The plug-in fails with the following error in the NetVault Backup logs:
The trace logs include the following message:
Cannot open library: libexpat.so.0: cannot open shared object file in vixDiskLib-16642.log.
To correct this problem, navigate to the /usr/lib directory, and create the following symbolic link:
CBT-based image-level backup fails
An image-level backup for which CBT has been enabled reports an error and fails.
The job fails with the following error in the NetVault Backup logs:
Failed to get changed disk areas.
This issue occurs when a snapshot exists on a virtual machine when CBT is enabled. For snapshots that exist before enabling CBT, the changeId parameter is not set. So, when the QueryChangedDiskAreas API is invoked, it returns an error. For more information, see http://kb.vmware.com/kb/1033816.
To correct this problem, do either of the following:
|
• |
Ensure that no snapshots exist on the virtual machine before selecting the Enable Change Block Tracking for VM check box. |
|
• |
Use the Reset Change Block Tracking option. This option reconfigures CBT on a virtual machine and allows you to run CBT-enabled backup that failed previously. For more information about this option, see Resetting CBT on a virtual machine. |
SAN transport reports errors when multiple backups access the same datastore
During a backup using the SAN transport mode, the following errors are reported:
San transport error: I/O Operation failed.
Error: One of the parameters supplied is invalid.
These errors are caused by a fault in the Linux kernel when handling SCSI reservation conflicts.
