UCS vNIC Creation Issue

[craines3847]

When creating the vNIC I can create 5 and the blades Associate with no Issue once I create the 6th is fails to Associate, and after a long period I get error "Remote-Invocation-Error: Out of interrupt resources"

Also at same time when Associating it gets stuck at the last line on the second screen shot.

What adapter policy are you using on the vNIC? Do you have enough interrupt resources available?

Using the Built-in Policy Win-HPN which is 512 Interrupts

[craines3847]

Changed to the Windows policy which is 8 interrupts, and it worked.

I guess the max interrupts is 2560??

[Wes Austin]

Correct. The 1400 VIC can have a max interrupt of ~ 3000 across all its vNICs per VIC adapter. So max number of vNICs that we can have with Win-HPN is 5.

If you mark the post as correct, it will be a lot easier for others to find the solution in the future.

Thanks.
