Table 2. Known issues

Known issue	Issue ID
Restores that span tapes fail with the following error: “SMTAPE: Bad block in read stream. vbn = xxxxxxxxxx, max_vbn = xxxxxxxxx”	13506
On NetApp ONTAP 8.1.7 Mode filers, the plug-in restores data correctly, but reports the job status as failed and generates a dump.	13515
When specifying a backup path, if you omit the starting slash, the job hangs.	29586
On Clustered Data ONTAP 8.3, backups are performed using TCP connections instead of local connections because the plug-in fails to get affinity information about volumes and tape devices on this OS.	29613
When performing a SnapMirror to Tape backup job, if you kill the NDMP sessions, the job hangs.	29721
Currently, BLI backups are not supported on Clustered Data ONTAP 8.3.	29723
On NetApp filers running ONTAP 7.0 and later, if you try to restore data from a Traditional Volume to a Flexible Volume, the job fails.
To perform backups to a virtual tape library, you must set the Device Block Size to 256K. For instructions configuring this setting, see the chapter on Managing Storage Devices in the Dell NetVault Backup Administrator’s Guide.
The backup option Delete Snapshot on Exit (SMTAPE_DELETE_SNAPSHOT) is only supported on ONTAP versions 6.5 P5 and later, 6.5 H2 and later, and 6.5 R2 and later.
If a filer reboots or there is a loss of network connectivity with the filer while the plug-in is running, the filer-attached drive goes offline with the message “Command Failed, Re-initializing Driver” when the plug-in tries to access the drive after the NAS Device is brought back online. After a few minutes, the drive recovers and becomes online, but you must perform a manual check before using the drive. To perform a manual check 1 In the Navigation pane, click Manage Devices, and then in the list of devices, click the applicable drive or the corresponding Manage Device icon. 2 On the Tape Drive Management page, click Check. If you had issued any load or unload requests before performing this procedure, try them again after the check.
When a job starts child jobs, the user logged on to NetVault Backup when creating the parent job remains the owner of the parent job, but the child jobs are owned by the default user. This issue can affect NetVault Backup Reports, Job Status page, and other functionality that depend on job ownership.

Upgrade and compatibility

•	Select the correct installation package on Linux: Starting with 10.0, NetVault Backup offers separate client-only and server-only installation packages for Linux-based systems. Both the server and the client packages are available in hybrid and pure 64-bit versions:

•	Hybrid server and client packages: The hybrid packages (LinuxX86HybridServer and LinuxX86Hybrid) are intended for Linux users who do not have a pure 64-bit-only requirement.

These packages let you upgrade from pure 32-bit as well as hybrid installations of NetVault Backup. The hybrid packages retain binary compatibility with all previous versions of 32-bit and 64-bit plug-ins. These packages also work on 32-bit systems that do not have 64-bit capability.

•

Pure 64-bit server and client packages: The pure 64-bit packages (LinuxX86Pure64Server and LinuxX86Pure64) packages are intended for pure 64-bit Linux distributions. If you have a specific reason that you cannot use any 32-bit components (for example, you are using a Linux distribution that does not run 32-bit code), use these packages.

The pure 64-bit packages cannot be used to upgrade existing pure 32-bit or hybrid NetVault Backup installations. You must remove the existing pure 32-bit or hybrid version and install the pure 64-bit version separately. To reduce confusion, warning messages have been added to both the upgrade and installation packages to ensure that you understand that they are not compatible.

Depending on your OS type, verify that you select the correct installation package to install the NetVault Backup Server or Client software:

•	LinuxX86HybridServer: Use this package to install or upgrade NetVault Backup Server on 32- or 64-bit Linux systems.

•	LinuxX86Hybrid: Use this package to install or upgrade NetVault Backup Client on 32- or 64-bit Linux systems.

•	LinuxX86Pure64Server: Use this package to install or upgrade NetVault Backup Server on pure 64-bit Linux systems.

•	LinuxX86Pure64: Use this package to install or upgrade NetVault Backup Client on pure 64-bit Linux systems.
