Npar fail over across two boxes.

I have 2 rx8640 servers, with total 4 cell and 32 processor.Curent confguration is with one npar each on boxes, which contains two cells.

Mu plan is to test failover of one npar to the other box by transfering liense through gicap, thais after failover one box would have 4 cells active and 2 npar on the box.

Is it possible, how can i deactivate the napr the single npar on the single complex.And how to actiovate the the single npar box from other box.

I think you guys have got the thig,

Pls advice me

If one of the box is going down.Wether I will be able to transfer the icap licences to other box and activate a new n par there.So i can have a fail iver there.

From what you say, each rx8640 is only using 1/2 of the cells now?

>by transferring license through gicap

This may not affect your testing but will that work if one of the servers has crashed?

Re: Npar fail over across two boxes.

Hi,

So do you actually *have* GiCAP, or are you just considering it? You don't really make that clear.

Anyway you can acheieve what you describe with GiCAP, but you do need to have a thrird system somewhere that acts as the GiCAP group manager. The group manager is able to "seize" the usage rights of the failed system. A good starting point would be reading this whitepaper here:
