HELP!!! My PureDisk Diskpool keeps going down
I am using netbackup 7.0 deduplication storage server . Have 1 master (also media) and 1 media. I rebooted the master server (after entering some license) and after that the diskpool issue started happening. At first i thought it was a licensing issue as I just entered in some license keys. However have reverted the changes but the issue persists. Disk Pool Name : DSK_POOL Disk Type : PureDisk Disk Volume Name : PureDiskVolume Disk Media ID : @aaaab Total Capacity (GB) : 16381.31 Free Space (GB) : 5721.40 Use% : 65 Status : DOWN Flag : ReadOnWrite Flag : AdminUp Flag : InternalDown Num Read Mounts : 0 Num Write Mounts : 1 Cur Read Streams : 0 Cur Write Streams : 0 bperror -disk keeps giving this error: Task sessin on start request on serverPureDisk:my_media_server on my_media_servergot an unexpected error. I try to run nbdevconfig -changestate to UP and it just does not work. Have tried rebooting,restarting services,still down. As fas as i can tell there is no issues on the disk. I have another media server connected to the same san with no issues. backup fails immediately with storage unit unavailable errors. Backing up to tape using the same media server is ok. The other thing is my media server. Am on hold on the support live queue for like an hour.....if anyone has any troubleshooting tips please help .thanks2.7KViews1like8Comments
CLI Command For Dedup Rates
NBU Experts, Do any of you know if there is a CLI command that can tell the dedup rate for all the images created, and stored in a PureDisk pool? For examaple, if I run bpimagelist on the master server I get some good info, but not the dedup rate for each image.

Advanced Disk Space v De-Dupe Disk Space - 5230 Appliance
Hi, We have a new 5230 appliance where the internal disk has been set up (by default) in the following way: Catalog 20% - around 930GB Advanced Disk 16% De-duplication Pool 64% We intend to backup to site A, then use AIR to replicate to site B (another 5230 appliance) where the backup will be eventually vaulted off to tape. However, some data will stay at site A until its expiry date (1 year). We have various retention times and clients. 1. Are there any calculations for the amount of catalog ratio to backups. Is 20% catalog to high, should I resize this. I know its an open question somewhat but is there any rule of thumb? 2. As you can see, I have a mixture of Advanced Disk and De-dupe disk. How do we balance between de-dupe space and advanced disk? What is the difference? We want to get the benefit of de-dupe for every backup so why wouldnt we configure the whole capacity to be De-dupe disk and have no advanced? Would I use Advanced Disk for some backups and De-dupe for others? So we would end up with: Catalog 20% - around 930GB De-duplication Pool 80% Could someone help explain my options? Kind RegardsSolved2.4KViews0likes3Comments
How to restore MSDP master/media server after disaster
Hello, This is my first post. We have two NetBackup 7.0.1 servers. Both W2008R2 ent. Both VMs. We use MSDP feature. Both servers have 10Tb drives to hold images. Catalog backup jobs are configured. Key file is copied over the network to another DC. Catalog restore process is clear for me. The question is: Are there any additional steps to restore CRDB? 10Tb drives? Could you please provide best practice/manual? Thank you in advance.Solved2.1KViews0likes2Comments
