Re: EVA 4000: Unmappable Hardware

Go to the EVA and in the rear of the disk enclosure, ensure that it has a Enclosure Address Bus assigned. If not, check your junktion box connection.

Re: EVA 4000: Unmappable Hardware

I check all cables seams all cables connected normaly.

In Controller Events logs I have

The device loop configuration has changed on a HSV200 controller's Fibre Channel port.

An HSV200 controller has updated the physical disk drive map for a loop pair.

The retry count for a task assigned to a Drive Enclosure Environmental Monitoring Unit has been exhausted.

and this three logs repeat every ~10 minuts.
On second EVA2 non of the described events appears

any idea?

Re: EVA 4000: Unmappable Hardware

Arman:

Are you running XCS 5.100?

Did this "just" happen while the EVA was running? (Already initialized)?

There is a known issue in XCS 5.100 that causes the EMU in Disk Enclosure 1 to reset/reboot/whatever and cause the shelf to look like it is unmappable. If you remove the EMU, wait 5 seconds and plug it back in... it may come back up with no issues. Check in CV-EVA to make sure.

From what I here, it may only effect EVA8000's, but I could be mistaken. I have a customer experiencing this issue and HP has confirmed it. Next release of the XCS "should" fix it, but it is a non critical situation, supposedly.
