I run a system comprised of 36 IBM Blade servers, a Hitachi 64TB SAN, a Data Domain backup suite and connection devices. I run Windows 2003 R2 (32bit) and Red Hat 4 (64bit). I have just come across a problem in that all the windows blades in one (of three) chassis are displaying my drive E: (which is/was a “Partition Basic NTFS” mount on the SAN) as a “spanned Dynamic” disk. This occurred to all the SAN mounts on this specific chassis at the same time. No one switched the disk format; it occurred just after updating the firmware on a Cisco MDS switch, though for the life of me I cannot see a correlation. I cannot have a non-fault tolerance mount with the data I am administering. Has anyone seen this before or can explain how this occurred? Does anyone know of a way to convert from Dynamic spanned back to a basic disk mount without losing data? Thanx.
