Hi
We have installed SLES11 SP1 on HyperV with IDE Controller and seeing some vague behavior.
SLES11 SP1*********
hsles11sp1:/ # cat /proc/scsi/scsi
Attached devices:

hsles11sp1:/ # ls /proc/ide/
drivers hdc ide1
hsles11sp1:/ # cat /proc/ide/ide1/hdc/media
cdrom
whereas the same commands on SLES11 GA behave…

It seems SLES11 SP1 on HyperV ( IDE Controller) doesn’t list disks under /proc/scsi/scsi.
Under /proc/ide/hd? …it just shows cdrom.
Any idea why this should happen ?
Also we tried changing the HyperV setting to SCSI Controller but OS fails to boot up both for SLES 11 and SLES11 SP1 …saying no hard disks found.
Appreciate any help!
Thanks
