RHEL AS4.8 device names for MSA2300sa vdisk volumes

[DavidWilliams]

We have ordered several HP StorageWorks MSA2300sa Controller, part number: AJ808A.

Can anyone tell me what type of device MSA2300sa vdisk volumes will show up as on RHEL AS4.8?

e.g. will they be /dev/sd* devices or /dev/cciss/c*d*p* or something else?

TIA,

David

I think as /dev/cciss ... as usual HP arrays. BUt not sure.

Hello David,

if the arrays attached to a Smart Array controller the device names will be like /dev/cciss/c*d*p*.

Regards,
Patrick

The array is in fact an MSA2312sa. The 2 volumes configured on it show up as /dev/sda and /dev/sdb and multipath devices /dev/mapper/mpath0 and /dev/mapper/mpath1.
We have a single dual-port SAS HBA in the server and a single MSA2312sa controller in the array, connected using a single SAS cable.

Here is some screen output in case you're interested:
