How to remove NetBackup Media Server Deduplication option (MSDP) configurations from a NetBackup environment.
Solution
Warning:- These steps will expire any images associated with the MSDP Disk Pool to be removed!!!!
NOTE: the script in step 10 is only available in NetBackup versions 7.0.1 with the latest dedup bundle from ET2233961 / TECH153190, 7.1.0.1 with the latest dedup bundle from ET2412409, 7.1.0.2 and higher and 7.5. Please upgrade to obtain this functionality.
1. Ensure a recent and successful hot catalog backup exists before proceeding.
2. Carefully expire only the images from the catalog that pertain to the Disk Pool to be removed. (NetBackup administration console -> NetBackup Management -> Catalog, 'Action' dropdown set to 'Verify', change 'Disk type' dropdown to PureDisk, and 'Disk Pool' dropdown to the MSDP Disk Pool name in question, then change the start date to past date/time to accommodate the oldest images, then click 'Search Now'. Select all the images found, right-click and choose 'Expire'.) Afterwards, wait for the NetBackup 'Image Cleanup' jobs to complete.
3. Set the Disk Pool to a down state using nbdevconfig (install_path\NetBackup\bin\admincmd):
3. Set the Disk Pool to a down state using nbdevconfig (install_path\NetBackup\bin\admincmd):
# nbdevconfig -changestate -stype PureDisk -dp your_MSDP_disk_pool_name -dv PureDiskVolume -state DOWN
4. Delete the Storage Unit in NetBackup administration console -> NetBackup Management -> Storage -> Storage Units
5. Delete the Storage Unit from any Storage Lifecycle Policies (in NetBackup administration console -> NetBackup Management -> Storage -> Storage Lifecycle Policies)
6. Clean up images using nbdelete and bpimage (install_path\NetBackup\bin\admincmd):
4. Delete the Storage Unit in NetBackup administration console -> NetBackup Management -> Storage -> Storage Units
5. Delete the Storage Unit from any Storage Lifecycle Policies (in NetBackup administration console -> NetBackup Management -> Storage -> Storage Lifecycle Policies)
6. Clean up images using nbdelete and bpimage (install_path\NetBackup\bin\admincmd):
#nbdelete -allvolumes -force
#bpimage -cleanup -allclients
7. Delete the Disk Pool from the GUI. administration console -> Devices -> Disk Pools
#bpimage -cleanup -allclients
7. Delete the Disk Pool from the GUI. administration console -> Devices -> Disk Pools
8. Run command (install_path\NetBackup\bin\admincmd): nbemmcmd -listhosts on the master server to list all the servers, take note of the NDMP machine type entry for the storage server in quesiton.
9. Delete the storage server credentials, storage server and the storage server NDMP machine type from the EMM database (nbdevconfig/tpconfig can be used to remove storage_server and creds, tpconfig found in install_path\Volmgr\bin):
9. Delete the storage server credentials, storage server and the storage server NDMP machine type from the EMM database (nbdevconfig/tpconfig can be used to remove storage_server and creds, tpconfig found in install_path\Volmgr\bin):
#tpconfig -delete -storage_server your_MSDP_storage_server_name -stype PureDisk -sts_user_id root
#nbdevconfig -deletests -storage_server your_MSDP_storage_server_name -stype PureDisk
# nbemmcmd -deletehost -machinename your_MSDP_storage_server_name -machinetype ndmp
10. Execute the PDDE_deleteConfig script to remove the MSDP configurations
Windows: <install_path>\Veritas\pdde\PDDE_deleteConfig.bat
UNIX/Linux: /usr/openv/pdde/pdconfigure/scripts/installers/PDDE_deleteConfig.sh
