In Case of Trouble
Problems Configuring HP-UX 11i
If the A5783A PCI Token Ring HBA is using a universally administered
MAC address, the MAC address is not preserved when the online
replacement (OLR) is performed, and the new HBA uses a different
universally administered MAC address.
If you plan to use online replacement for an A5783A that uses a
universally administered MAC address and is installed in an HP 9000
L-Class, N-Class, or Superdome system, you are affected. Note that the
universally administered MAC address is used mainly with SNAplus2.
Action: Change the configuration file for SNAplus2—or any software
that uses the A5783A HBA—to use the new HBA's universally
administered MAC address.
When you change the configuration file, the universally administered
MAC address inconsistency problem is fixed. This problem is similar to
what happens without OLR if an A5783A HBA fails: you must power off
the system, replace the HBA, and then power the system back on;
however, the configuration file issue exists.
Unsupported HBAs: Online addition and replacement (OLA/R) is not
supported on HP-UX 11i for these PCI HBAs:
• A5801A HIPPI
• A5838A SCSI/100BT
• A5856A RAID
• A6092A HyperFabric
