MSA 1000 & EVA 8100 storage connectivity together at a time

I have a DL580 server with the RHEL3 OS (Kernel Ver 2.4.21), 3 FC QLA2342 (Firmware Ver 3.03.19, Driver Ver 7.07.05.02) connected to a MSA1000 using 2 FC (8 LUN) running smoothly.

I want to connect the server with another one FC (8 LUN) with EVA 8100.

Is it possible to connect all (MSA 1000 & EVA 8100) storage together with the server at a time?

I already configured 8 LUN in EVA 8100 using one FC for DL 580 but I have seen 24 LUN in the Server (Using command : hp_rescan). Why?

Do I need to install multipath (MPIO) once again to resolve this issue?

Hi,
the MSA1000 controller has originaly active/passive firmware
the EVA4x/6x/8x controllers are only active/active from the beginning

Thats why the multipathing driver for active/passive sees only MSA1000 LUNs correctly and for the EVA 8100 LUN there is no multipathing installed yet and you see it the 8 LUNs more then once

The coexistence table for linux can be found here:

the pain is one part of the reality
