Netbackup Appliances 5230 with PureDisk: How many streams?
Hi all, We recently migrated to Netbackup Appliances running Netbackup 7.6.0.1 (Appliance version 2.6.0.1 ) We are running 2 appliances per site, each site is its own NBU domain (We use AIR to replicate). Each appliance is configured with a 70TB PureDisk volume. We are quite new to PureDisk that is running on these systems, but at this moment they are limited to 80 streams maximum in the diskpool object (Which seems pretty low to me) At the moment we are running out of resources due to this maximum that has been set. What is the maximum streamcount a 5230 Appliance PureDisk can safely handle? Note that we are using AIR to replicate all our images, but replication is being done during the day, not during backup times... Any advice is greatly appreciated! Thanks!1KViews1like2Comments

Hi, I am troubleshooting SPAR replication issue on 6.6.3 PureDisk. On the Destination Storage Pool SPAR jobs start and keep being queued with 0% progress until 24h watchdog kills them. On the Source Storage Pool the SPAR job is killed by watchdog after 4h at 33%. Tried to run update agent configuration (the Source SPA is an Agent on Destination pool) using the "Config File Update" but that job got queued at 0% and is not progressing on the target SPA. I have just re-activated - set all the settings from scratch - the SPAR policy on the Source Storage Pool. The SPAR activation job completed successfully on the Source SPA. Ran SSH session from one to another and the other way. Any ideas where is the connection problem? SSH keys? Strange. Any help or tips welcome!1.1KViews1like2CommentsCLI 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. Thanks, AVazquez2.6KViews0likes7Comments
Any recommendations for volume manager and file system type for MSDP on Linux...
Hi Forum, I've had a quick search through the DeDupe Admin Guide for v7.5 and I couldn't find any recommendations for volume manager or file system type for the MSDP database and/or data spaces. I guess an appliances uses VxVM and VxFS - but what else might be suitable if we were to build our own Linux based MSDP media server. The local server disks will re RAID-1, and the SAN LUNs will be: - MSDP DB on one x 2 TB LUN from 3PAR - MDDP data on four x 16 TB LUNs from 3PAR (i.e. 4 x PG of RAID-6 6D-2P) I guess my question really relates to the MSDP data space - I was thinking of a simple logical volume of the four LUNs concat together and an ext4 file system on that logical volume. Or might I be better off in carving the MSDP data storage as a concat 2 x LUNs (i.e. 2 x PG of RAID-6 14D-2P)? And I assume a sector cluster/blocking factor of 64 KB is appropriate for ext4, just as it is for NTFS. Anyone have any advice, or willing to share what they did and whether they ripped anything up and started again?1.2KViews0likes2Comments
fakeFPCheck reports corruption while reclaiming deduplication space
I am reclaiming deduplication storage space manually on a 5200 appliance. I am following the process in TECH180659. I see a lot of these type of messages: January 21 08:58:24 INFO [1082194240]: fakeFPCheck: DO 53c8979cafabfcc54c82cf7900fa465a is corrupt January 21 08:58:26 INFO [1082194240]: fakeFPCheck: DO 546d2e925f2a6325c52884556187e102 is corrupt And running the garbage collector doesn't seem to clean them up as they show up again the next passof running CR queue processing (/usr/openv/pdde/pdcr/bin/crcontrol --processqueue). Is there some way to clean up these corrupt fragments and reclaim the storage space? Thanks, Wayne482Views0likes1Comment
NetBackup PureDisk Pool - Segments folder
Hi all, We have a PureDisk pool which fills up rather quickly. On inspection there is a Segments folder (\history\segments) on the PureDisk media server which has over 100GB of data. I haven't been able to find much information on what the data is used for, or if I can safely move or delete the data. Is anyone able to shed some light on this? Thanks!662Views1like2Comments
