Hi all
I am experiencing a DRIVE's issue with netbackup since I've changed the SFP component.
I have a backup server (Hp ProLiant DL360p Gen8) with "PCIe 3.0 Low Profile x8" card.
The backup server is linked to a Symantec tape library via a ICSI cable + SFP component.
Last week all the "PCIe 3.0 Low Profile x8" LED were flashing, no backups performed and got the following error message:
RD-BMO-BCK01 login: NOHZ: local_Softirq_pending 100
rport-2:0-0: blocked FC remote port time out: removing target and saving binding
After investigation, I had to replace the SFP component and restart both servers. Now no LEDs are OK but I am still not able to perform backup.
When checking at the "DRIVE MONITOR" menu, I can see that my drive is in DOWN-TLD status. When right-click I can see severals options such as "Up Drive".
Despite of this the "DEVICE/DRIVE" menu report that the drive is enabled.
All my tapes are in ACTIVE mode.
Since I've rebooted I lost the Netbackup's client conenction on my workstation.
Can someone help me to troubleshoot ?
In advance, I thank you for your help.
Damien

Confused...you have one robot and one drive yet tpconfig says you have two robots and two drives one pair of which is a bit duff. I'd delete the stunits, all drives, all robots, start from scrach, ensure theres one and only one of each at the OS (assuming thats the real number you have) and then and only then recreate netbackup devices, stunits.jim

Hello,
Windows, Linux, UNix Media Server?
If I understand correctly, you did not try "Up Drive" yet?. Try it and check if it goes to TLD (UP) state. Drives does not go to UP state automatically once thinks are ok.
If not, check OS debug logs whats the problem - in this cases problem is usually on OS or HW level, probably related to SFP change.

Certainly looks like Linux message above.
Run 'scan' command to confirm you can see drive and changer.
If that's good then try Device Configuration Wizard to confirm it also sees the devices.

Hi all
Thank you for your replies!!
michal1967 and Marianne : The OS is a "Red Hat Enterprise Linux 6"
michal1967: I did an "Up Drive" and the control's status pass from DOWN-TLD to TLD.
Will Restore: can you tell me how to run a 'scan' command and how to launch the "Device Configuration Wizard" because I'm not familiar with Netbackup
In advance, I thank you for your replies.

I did an "Up Drive" and the control's status pass from DOWN-TLD to TLD.
Does the drive stay UP (TLD) when you start a backup?
To ensure all devices are seen at OS-level, run:
cat /proc/scsi/scsi
scan command is in /usr/openv/volmgr/bin.
Please copy the text output of scan as well as 'tpconfig -l' (in same folder) and post here.
This output will tell us if it is necessary to re-run the Device Config Wizard.
(Will give details if needed.)

Did it ever work? If so , apart from described, any other change? Any other devices on the same server...any other port you can zone in the drive and verifty temporarily? (Unclear if its direct attached or not). The long and short as detailed by others is: no point in thinking about netbackup until the OS can use all drives successfully...and for this just use Os cmdline and tar, writing and reading to all drives in turn.Isnt there some OS level cmd needed to make it generate a device tree for what it could believe to be a new drive?Jim

Hello Marianne and Jim
I am really sorry for the late reply.
I've succesffully restarted the Netbackup client on my workstation by resolving a network issue on my Backup server.
In fact, I've a BOND interface which include ETH0 and ETH1 which are on two different Vlans.
So I've done some network configuration changes and I have to see if the backups will run.
I'll wait until monday before providing you the two commands.
