Multiple paths to a MSA30DB ?

Hi Guys,

is it possible to configure dual SCSI paths to disks in a MSA30 dual bus enclosure via a dual channel SCSI HBA ? The server in question is a rp3410 and I am trying to find out whether I can have 2 PVlinks for each disk.

Thanks,
Jozef

Re: Multiple paths to a MSA30DB ?

Hi Jozef,

no, not with the dual bus module.

There are 3 different modules available for the msa30:

1) SB - single bus (all disks on 1 bus), 1 connector
2) DB - dual bus (left/right half of disks on 1 bus each), 2 connectors

3) MI - multi initiator - 2 busses for each half of disks, 4 connectors


You need 3) MI module!

(it's working only with hp-ux - it's exactly what you need)

Hope this helps!
Regards
Torsten.

Hello Torsten,

thanks for your prompt clarification. It was not really clear from the user guide, but the 4-port bus module makes sense.

Jozef
