Re: FC60 Performance Problem
- which OS do you use for backup (hpux, windows)?
- how is LFC60 connected to host - direct, hubs, switches? I you use switches check port mode (N-port, NL-port, error rates etc). You can post supportshow here;
- use amlog utility to read FC60's logs. Maybe there'are some hardware problems?

Re: FC60 Performance Problem
Using Veritas NetBackup. System is at HPUX-11.0. Both FC60's are connected direct to host. Nothing shows up in the AMMLOGS. I also have to add, these are Oracle filesystems.
Thanks, Joe

Re: FC60 Performance Problem
- tdutil /dev/tdX for each FC HBA (fcmsutil /dev/fcmsX for old Tachyon cards);
- amlog -a output for LFC60 for the backup period;
- amdsp -a for LFC60;
I think if you have both FC60s connected to one machine and one performs good but another do not then the problem not in the host/software, but in FC60/cables/dedicated FC adapters (but... there are device files for each device... do you think they can be a problem?)

Re: FC60 Performance Problem
Come to find out that according to the Oracle DBA there was many new redo logs that were backed up this past backup. We will monitor and see if we have same problem this upcoming backup as things should be back to normal then.
Appreciate the assistance and sorry to have you on a wild goose chase.
