Error opening the snapshot disks using given transport mode: Status 23
Hi, Bit of a strange one this ! 7.6.0.3 HP-UX Master, VMware backups using SAN transport to 5230's as the backup hosts. All was working ok. New LUN added, made visible to the appliances, cant back any VM up on new LUN. Get the status 23 error. My storage guy assures me LUN has same access as all other LUNs so should be ok. Now a few other previously working backups have started to fail. Ones residing on the old LUNs ! I have enabled vxms logging up to 8 but all I see in the logs is below. Its says disk open error. I know that, just need to know why !

Adding LTO6 drives to library with LTO4 drives
Hello, Yesterday we added several LTO6 drives to our SL8500 library that has LTO4 drives. After we installed the new drives, I zoned them to one media server, ran the wizard and it discovered a new robot. Now I have the original ACS(0) and ACS(2), which is the new robot. I also configured a new storage unit on the new media server for the new tapes. I inserted 10 LTO6 tapes and manually moved them to a volume pool called LTO6_TEST that I just created. I ran a test backup using the new media server and it ran successfully. This morning I added 10 more drives to the library and when I ran the Robot Inventory, it tries to add the tapes but when it goes to the first of the LTO6 tapes that already existed there, it shows the following: Update failed: could not add new media ID 'M00146' into robot Insert media failed: media ID not unique in database (34) And then it stops and doesn't add the new media. What am I doing wrong? Also, what would be the best practice for a libarry with 2 different kinds of drives, LTO4 and LTO6?Solved1.8KViews3likes9Commentscan catalog files of a backup to be moved manually to different domain for restore?
Since the tape import takes long time, i am wondering after backup completed, if we can move some catalog files from master to different domain for restore instead of importing tapes.

Hi All, A backup is taken in a server ( server1) which is running Netbackup 7.6 . Used Tape Media for backup ( say ABCD). If i ship the media to different environment which is runniong 7.6 with the same hostname ( server1) and the catalog is also copied. For this scenario, do i need to do cat_import ?Solved3KViews3likes24CommentsNetbackup Questions for level 1 and level 2

Hi All, I have a real world issue and I managed to resolve it, but I am more insteresting in the why theNET_BUFFER_SZ works. Below is the description: Issue There is a newly installed NBU client at 7.5 level in the HP 11.31, IA64 platform. When I try to backup the oracle database I found out the backup speed is slow and this scenario also happens for the files backup. The file backup policy is defined to backup the path at /stand which has about 366M. Error The job detailed shows the speed is at 1mb/s for the file backup, but manually copy the files between the client and the master is faster. The bpbrm, bptm ,bpbkar process run fine without any issue, but we see the bpbkar spend 7 minutes to send out 366M data, the speed is 366M/7=52M/minute=0.87M/second 13:00:33.197 [20457] <2> logparams: bpbkar32 -r 604800 -ru root -dt 0 -to 0 -bpstart_time 1394686961 -clnt domsgs-BackupDB -class test_stand -sched full -st FULL -bpstart_to 300 -bpend_to 300 -read_to 300 -blks_per_buffer 512 -use_otm -fso -b domsgs-BackupDB_1394686661 -kl 28 -use_ofb 13:00:33.301 [20457] <2> bpbkar SelectFile: INF - Resolved_path = /stand 13:00:33.301 [20457] <4> bpbkar SelectFile: INF - VxFS filesystem is /stand for /stand 13:00:33.335 [20457] <2> bpbkar resolve_path: INF - Actual mount point of /stand is /stand 13:00:33.353 [20457] <2> fscp_is_tracked: disabled tla_init 13:07:22.596 [20457] <2> bpbkar resolve_path: INF - Actual mount point of / is / 13:07:22.596 [20457] <4> bpbkar expand_wildcards: end backup for filelist /stand 13:07:22.596 [20457] <4> bpbkar main: INF - Client completed sending data for backup However, run the bpbkar to just read the data from the /stand speed 5 seconds: bpbkar -nocont -dt 0 -nofileinfo -nokeepalives /stand 15:25:00.411 [22525] <2> bpbkar SelectFile: INF - Resolved_path = /stand 15:25:00.411 [22525] <4> bpbkar SelectFile: INF - VxFS filesystem is /stand for /stand 15:25:00.412 [22525] <2> bpbkar resolve_path: INF - Actual mount point of /stand is /stand 15:25:00.419 [22525] <2> fscp_is_tracked: disabled tla_init 15:25:05.063 [22525] <2> bpbkar resolve_path: INF - Actual mount point of / is / 15:25:05.063 [22525] <4> bpbkar expand_wildcards: end backup for filelist /stand 15:25:05.063 [22525] <4> bpbkar main: INF - Client completed sending data for backup 15:25:05.063 [22525] <2> bpbkar main: INF - Total Size:366915603 Reading the bptm log, found out: 12:57:46.126 [4748.8120] <2> io_set_recvbuf: setting receive network buffer to 1049600 bytes Job detailed shows: bptm(pid=2572) waited for full buffer 2370 times, delayed 92131 times Environment: Master/media: windows 2008R2 NBU7.5 Client: HP unix 11.31 IA 64 NBU7.5 Solution: In the client: echo "0" > /usr/openv/netbackup/NET_BUFFER_SZ In the master: Create the file NET_BUFFER_SZ at /install_path/netbackup and assign the value 0 into this file.
