Hello,

Can anyone tell me if the TSM SnapDiff option is supported with ONTAP 8.0.1 7-Mode?

Every IBM or NetApp document I can find says that its supported with ONTAP 7.3 and above, but nothing explicility says ONTAP 8.0.1 7-Mode is supported.....

Thanks,

New for TSM client version 6.2.2

The following features are new for IBM® Tivoli Storage Manager in Version 6.2.2:


>> Unicode support for NetApp snapshot-assisted progressive incremental backup

If you run snapshot difference incremental backups, some files might not be backed up because their names contain non 7 bit ASCII characters. Support for non 7 bit ASCII file names has been added to NetApp Data ONTAP version 7.3.3 (or later) or 8.0 (or later). If you migrated to a file server version that supports non 7 bit ASCII file names, use the option createnewbase to create a new base snapshot and use it as a source to run a full incremental to ensure that the backup of any files that might have been skipped previously.


Createnewbase
The createnewbase option creates a base snapshot and uses it as a source to run a full incremental backup.

Some files might not be backed up when the snapshot difference incremental backup command is run. If the files are skipped, you can run a snapshot difference incremental backup with the createnewbase option to backup these files. See Snapdiff for a list of reasons why a file might not be backed up when the snapshot difference command is run.

NetApp Data ONTAP versions 8.0 and versions lower than 7.3.3 do not support file names that are not within the 7 bit ASCII character set. If you upgraded to NetApp Data ONTAP version 7.3.3, that supports file names with non 7 bit ASCII characters, use the createnewbase=migrate option to create a new base snapshot and run a full incremental backup. The createnewbase=migrate command backs up any files with non 7 bit ASCII names, that might have been skipped previously.

  
Supported Clien

This option is valid for the following clients:
All Windows clients except IA 64 bit
AIX® 64 bit clients
Linux x86/86_64 clients
Enter the createnewbase option on the command line. Specify this option with the snapdiff option.

Sp
ecifies that a snapshot difference incremental is run. If Tivoli® Storage Manager detects that the NetApp Data ONTAP file server has been migrated from a version that does not support unicode-enabled file names to a file server that does, a warning message is recorded to the error log and the Tivoli Storage Manager server activity log. The warning message indicates that you must run a full incremental backup and logs a return code of 8 even if the operation completed successfully.
This parameter is the default value.

YES
S
pecifies that a full incremental is run by creating a new base snapshot and using it to run a scan-based incremental backup. Use this option to backup any file changes that might not have been detected by the snapshot difference API.
If the operation finished successfully, the command ends with a return code of 0.
It is recommended that you do not set creat
enewbase=yes for any schedule that runs a daily snapshot difference backup. Instead, create a separate, monthly schedule that has the createnewbase=yes option.

IGNore
Spec
ifies that a snapshot difference incremental backup is run when Tivoli Storage Manager detects that the NetApp Data ONTAP file server was upgraded to support Unicode file names.
The IGNor
e parameter is different from the No parameter because Ignore suppresses the warning message. Instead, an informational message is recorded in the error log and the Tivoli Storage Manager activity log that tells you to run a full incremental backup.
If the command finishes successfully, it returns a code of 0.
Use the IGNor
e parameter if you have upgraded the NetApp Data ONTAP file server to support Unicode but you have not yet run a full incremental backup. This option is used only when the Tivoli Storage Manager client has detected that the file server was migrated and a full incremental has not yet been run. The option is ignored for all other times.

MIGRate
Spec
ifies that if the NetApp Data ONTAP file server was upgraded to a version that supports Unicode file names, a base snapshot is taken and a scan-based incremental backup runs. The MIGRate parameter is different from the YES parameter because the MIGRate parameter creates a base snapshot only when Tivoli Storage Manager detects that the NetApp Data ONTAP file server version was updated. The YES parameter creates a base snapshot every time the command is run.
After the incremental backup finishes, no additional migration-related messages are recorded to the error log or the Tivoli Storage Manager server activity log. When the operation finishes, the command ends with a return code of 0.
Use the MIGRa
te parameter if you have upgraded the NetApp Data ONTAP file server to support Unicode but you have not yet run a full incremental backup. The MIGRate parameter is ignored if the NetApp Data ONTAP file server has not been upgraded.

Hope this helps

TSM Client version 6.2.2 with ONTAP 8.0.1 7-mode is supported... Thanks

Thank you djordan!

Can you also confirm if 8.0.1 7-mode contains the File Access Protocol (FAP) enhancements that 7.3.3 added to fix the non 7-bit ascii problem?

I want to be able to confirm what level functionality its equivalant to on the ONTAP7 track.

Thanks, -Shaun
