Oracle Solaris Might Run Out of MSI-X Vectors
Issue:
Oracle Solaris limits the number of MSI-X vectors to 32 per IPL. Network interface cards (NICs)
and host bus adapters (HBAs) are all assigned to IPL 6. If there are a large number of adapters in the
Sun Fire X4470 Server that use MSI-X for interrupts, you might run out of MSI-X vectors. If this
occurs, the system sends a message similar to the following:
Apr 15 23:22:54 ban21uut058spare2 pcplusmp: [ID 475383 kern.warning] WARNING: No
interrupt vector: pciex8086,10fb instance 1

Sharing vectors: pciex8086,10fb instance 11 and pciex8086,10fb instance 1
Affected Operating Systems:
■ Oracle Solaris 10 8/11
■ Oracle Solaris 10 9/10
Workaround:
1. Download Oracle Solaris patch 146025-01.
