SnapDrive for Windows identifies bootable LUNs and prevents you from performing some of the operations you would normally perform on a nonbootable LUN.
SnapDrive detects both bootable LUNs (SAN booting) and nonbootable LUNs and differentiates between the two in MMC by representing each LUN type with a unique icon. SAN bootable LUNs are represented by an icon containing a disk with a red letter “s” in the upper left corner.
