Re: Looking for sites with TSM 4.X running on HP-UX server
Mark (and anyone else monitoring), Update on our situation, which I think was similar to yours... We've been having erratic TSM server hangs, but only the TSM server, the OS and other minor apps on the system are OK. There were no evident bottlenecks or problems. Yesterday, I reviewed the actlog for the previous 4 days and saw many I/O errors like this: 02/18/02 12:04:05 ANR8302E I/O error on drive DRIVE4 (/dev/rmt/11m) (OP=FSR, CC=-1, KEY=FF, ASC=FF, ASCQ=FF, SENSE=**NONE**, Description=An undetermined error has occurred). Refer to Appendix D in the 'Messages' manual for recommended action. I searched the actlog for mount msgs, ANR8302E msgs, and dismount msgs. Whenever tape volume 000432 was mounted, it was followed by many 8302 msgs, and never saw a dismount for that tape. Conclusion: there must be something wrong with that tape! I marked it unavailable and have not seen the hang in the last 24 hours. We know that tape was used a few days prior to the hangs for backup of an NT server that had known disk (FAT) corruption, but we thought it was in the recycle bin which is excluded. We were then constantly doing storage pool backups which we think mounted that tape and caused the hang when it reached the corruption on the tape. I am now concerned that an apparent media fault can cause TSM to hang. I have an open PMR with Tivoli. I guess the moral of the story is -- investigate I/O errors thoroughly! Robin Sharpe Berlex Labs
Re: Looking for sites with TSM 4.X running on HP-UX server
Robin, We've been having some very interesting conversations with HP and Tivoli about the application problems. They gone through all of our stuff and would like to compare our kernel parameters with someone else that is running 4.1 on HP 9000 L-Class server. Could we get a copy of /stand/system the output of sysdef and kmtune -l Let me know how we can repay the favor. thanks, mark -Original Message- From: Robin Sharpe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 1:35 PM To: [EMAIL PROTECTED] Subject: Re: Looking for sites with TSM 4.X running on HP-UX server Ok Mark, Here is my swlist -l product: (See attached file: swlist)(let me know if you can't get the attachment, I'll insert the text). We haven't had such serious problems (no corruption). 4.1.4.1 has been pretty stable for us... until last week. So far, after the patches this morning, it looks pretty good. I had heard that the earlier mods of 4.1 were buggy... maybe that is at the root of your trouble? We have about 26 unix (HP and Sun) and 50 NT clients. We also have another TSM on an IBM F50 with an ATL P3000, which we are migrating from. We plan to move it to another location after migration. Our L2000 has two 550Mhz procs, and 2GB RAM. Database and disk storage pools are on two HP 2100 arrays... we plan to move the database and logs to the XP512 when it is online. Good Luck Robin
Re: Looking for sites with TSM 4.X running on HP-UX server
Robin, Here is a quick update. We've got Tivoli and HP talking. TSM 4.1.5 is a 32-bit application and it runs into an issue with one of the pthreads dying, causing the app to hang. When we went from 4.1.0 to 4.1.5 due to a known bug, the app changed around version 4.1.2 from many processes to one process with many threads. Hopefully Tivoli can get a fix for this very soon. We can let you know what we come up with. I and my group do have concerns about QA testing and the level of commitment for HP platform support. thanks, mark -Original Message- From: Robin Sharpe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 1:35 PM To: [EMAIL PROTECTED] Subject: Re: Looking for sites with TSM 4.X running on HP-UX server Ok Mark, Here is my swlist -l product: (See attached file: swlist)(let me know if you can't get the attachment, I'll insert the text).

Re: Looking for sites with TSM 4.X running on HP-UX server
Mark, We are running TSM 4.1.4.1 on an L2000-5x, HP-UX 11.00. We have an HP 20/700 library with 10 DLT8000 drives, each on its own SCSI bus. We are in the early stages of a SAN implementation (with HP XP512 disk) and have just added 2 A5158A fiber cards to the L2000. At about the same time we installed them, we noticed erratic hangs on the TSM server, which eventually clear up... but the effect on TSM operations has been pretty bad. Just applied some patches to HP-UX about an hour ago... will let you know if it fixes things. What is your specific problem? What is you environment (server, library, etc.)?

Re: Looking for sites with TSM 4.X running on HP-UX server
Robin, Great to hear from you! We are backing up 60 UNIX servers and 220 NT/W2K servers with 15TB of EMC and 1.5 TB of NetApp to two L-Class boxes each with 4 440MHz procs, 12 GB RAM and an ATL P6000 w/16 drive tape library each. TSM 3.7.4 was very stable and our only problem was keeping pace with the rapid increase in new servers. When we went to 4.1, bugs started to crop in and caused stability issues. We've had horrible and frustrating experiences with Tivoli support. In 4.1 we ran into a known bug that corrupted the database. We applied all of the patches required by support (getting us up to 4.1.5) and now we are running into a thread errors. One of the threads will crash and bring down the app. Would it be possible to share the output of swlist ? I'm hoping that there may be a patch that you have already installed that we have not. thanks, mark -Original Message- From: Robin Sharpe [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 12, 2002 11:08 AM To: [EMAIL PROTECTED] Subject: Re: Looking for sites with TSM 4.X running on HP-UX server Mark, We are running TSM 4.1.4.1 on an L2000-5x, HP-UX 11.00.
