The disk is offline because of policy set by an administrator. You have just installed or cloned a VM with Windows 2. Enterprise or Datacenter or you have upgraded the VM to Virtual Hardware 7 and under Disk Management you get an error message saying: "the disk is offline because of policy set by an administrator". This is because, and this is by design, all virtual machine disk files (VMDK) are presented from Virtual hardware 7 (the one of ESX 3.
VMs as SAN disks. At the same time, and this is by design too, Microsoft has changed how SAN disks are handled by its Windows 2. Enterprise and Datacenter editions. Hello everyone, and welcome to the unofficial list of which OSes work and which don't in Microsoft Virtual PC 2004. I hope this site helps you! A must-have compilation of useful Linux tools across a wide range of categories, including links to numerous reviews and user recommendations. In fact, on Windows Server 2. Enterprise and Windows Server 2. Datacenter (and this is true for R2 too), the default SAN policy is now VDS_SP_OFFLINE_SHARED for all SAN disks except the boot disk. Having the policy set to Offline Shared means that your SAN disks will be simply offline on startup of your server and if your paging file is on one of this secondary disks it will be unavailable. Here's the solution to this annoying problem. What you have to do is first to query the current SAN policy from the command line with DISKPART and issue the following SAN commands: = = = = = = = = = = = = = = = = = = DISKPART. EXEDISKPART> san. SAN Policy : Offline Shared= = = = = = = = = = = = = = = = = =Once you have verified that the applied policy is Offline Shared, you have two options to set the disk to Online. The first one is to log in to your system as an Administrator, click Computer Management > Storage > Disk Management, right- click the disk and choose Online. The second one is to make a SAN policy change, then select the offline disk, force a clear of its readonly flag and bring it online. Follow these steps: = = = = = = = = = = = = = = = = = =DISKPART> san policy=Online. All. Disk. Part successfully changed the SAN policy for the current operating system.
