Change second SCSI to virtual - Cannot open the disk .... or one of the

[ckaye]

Trying to setup a cluster-in-a-box. I have W2K3 Enterprise installed on SCSI Disk 0:0. With the guest powered off i added a second 500Mb quarm disk to SCSI 1:0 and the second SCSI Controller automagically appeared.

If i leave the second SCSI controller bus sharing set to NONE i can power on the guest. When i set it to VIRTUAL (required for clustering) i can not power on the guest. I get:

Cannot open the disk ..... or one of the snapshot disks it depends on. Reason: Invalid argument.

Please help!

You might want to provide more informations on your setup eg. type disk - Virtual or RDM.

The following link might be helpful.

In order for the VMDK to engage in Virtual SCSI Bus sharing you need to have created a 'thick' disk. This needs to be done from the service console using vmkfstools, the command for creating a 4gb disk would be;

vmkfstools -c 4096m -d eagerzeroedthick /vmfs/volume/whatever your target vmfs3 file system is called/diskname.vmdk

Simon is correct....I ran into same issue when creating the disk thru the VI client....you have to create the shared disks using the command line.......
