add Hard disk but Unknown
Posted on 2011-10-12
On VMware ESXi with SAN and Storage, There are some Windows 2008R2 servers runing.
I want to add Hard Disk to one server as D drive, and added hard disk. Normally, There would be no prpblem
however, the attached hard disk seems to be not working.
I opened the start > Administrative Tools > Computer Management
DISK1 "Unknown" status. it says "Offline"
Normally, I can set up Volume but, something is strange with this new virtual disk.
Please let me know what is happening ? how can I format this disk?
