We have a 3-node MSCS setup for Exchange 2007. I understand from V4 configuration maximums that we only have maximum of 4 IDE controllers for either Disk or CD-Rom.
We have used up all the IDE for Shared RDM LUM mapping to the Exchange servers i.e. IDE 0,1,2,3 have 144GB shared Raw lun mapped respectively.
We have a challenge to add additional storage group to this setup (mount additional shared RDM Lun) to help increase the number of storage group, but i seem not to have additional IDE and there's a requirement from this document as below:
"A separate virtual adapter must be used for clustered disks"
Please i need your help.
