PERC 4 - Media Changer on second channel

[Chris_Purcell at Dell.com]

If the card you mentioned is truly the card being used, you can not set the channels to a scsi mode. The PCI raid controllers are just that, RAID controllers, they have no scsi mode.
 
The onboard scsi/raid controllers that are activated by a ROMB key normally have the ability to change between modes though, so if you have an onboard raid controller, you may very well be able to set the second channel in scsi mode and attach a tape device.
 
With only the PCI Perc RAID controller, you will need a secondary SCSI controller to attach a tape device.

Hi Mark,

Thx for your answer.

But, if the second channel is'nt configured in RAID, can we use our device ?

I can't test before putting the machine in datacenter. The device is
already in datacenter.

In a few day, the new machine will be installed. I would like to know if
the media changer will be able to be connected to the server.

thx.
