Chapter 3 Notes
79
• On Windows 2000, when an RV is unmounted, the RV access restriction is changed to Not
Ready. Accordingly, when a volume in a multi-partition configuration is unmounted, all
volumes (partitions) on the relevant disk cannot be read or written. After that, another
partition on the same disk cannot be accessed to read/write or be flushed by the iSMrc_flush
command until the RV is mounted by the iSMrc_mount command.
• Unmounting using the iSMrc_umount command must be executed in the status in which only
one mount point (drive letter or NTFS folder name) is set for the target volume. If no mount
point or multiple mount points are set, unmounting cannot be executed. For this reason, this
setting is unavailable for an operation procedure such as deleting all mount points using the D
option of the MOUNTVOL command before unmounting. When multiple mount points are
set for a volume, use the D option of the MOUNTVOL command to set only one mount point
for the volume, and then unmount the volume.
