Every since we upgraded Omniback 3.50 to 4.10 we have had a lot of problem with out HP surestore 6/140 library. HP have changed "everything" on it and upgraded the firmware several times, changed GBIC??s (both on the library and the server). The last call from HP is that we should replace all DLT tapes with new ones (meaning that our tapes are dirty and caused the problems)
I would like to know if you have similare problems with your HP Surestore library.

which problems? Explain in details. Post LTT report here (as attachment). Are you sure that nothing else changed with OB upgrade?

HP have installed the latest FW.

library is connected to FC and every adapter is in loop (why not fabric?) with alpa=01. I should know how lib is connected to host/SAN, using hub, switch or direct to HBA.
Anyway it's good idea to try new tape to check and tell HP if tape is the cause or not.
If your other libraries are in the same config I recommend you to compare reports for them and upderstand what differences do you have.
So I need:
- connectivity description
- which devices used (sw, hub, direct)
- which server you have (model, OS);
- are all libs have same config;
- try new tape and what are results.

the 6/140 lib. is connected directly to three HBA??s (1HBA serve 2 DLT 8000 drives). The server is a L2000 with 2CPU, 2GB, HP-UX 11.00.
The other libraries are:
HP 4/48 (A4855A) DLT 7000, FC-SCSI MUX
2 * HP 2/28 (A3546A) , direct attached -SCSI
All have "203":
crw-r--r-- 1 root sys 203 0x086000 Jan 19 2002 robotics_0
We have 2 cell servers in a MOM environment,
cell server A have the 6/140 and one 2/28 library and cell server B the other two. Cell server A is also MOM, media and license server.

all these should be ok. Please install HP Library and tape tools and generate support ticket and attach here. LTT is available from http://www.hp.com/cposupport/information_storage/s
I will check library's health completely

There are errors on the drives. Drives are reporting 33C and 37C temperature. I know that max operating temp for galactica is 35C. So I recommend you please check environment:
- cold conditioned air should blow to the front of the library;
- hot air should be taken away from the rear;
- from the front and rear should be enough space for proper air conditioning (let's say, 60cm both);
- lower air conditioning T to 19C.
After doing all these please try to do backup. If errors will occur again do LTT support ticket again and check reported temperature.
Please pay attention to environment because excessive T shortens life of library and tapes inside. For more detailed info please refer to user's guide

I'm sure you have probably already done all the standard HP-UX SAN checks, turning off ESM, applying all the patches, etc. anything you can tell us about what the SAN configuration settings are can help.
