Importing Dynamic Disk Groups
Chapter 3 79
• A deported dynamic disk group cannot be imported if another
dynamic disk group with the same name has been created since the
dynamic disk group was deported.
• When a dynamic disk group is imported, the system stamps its host
ID on all disks in the dynamic disk group. A dynamic disk group
import fails if one of the disks is stamped with a host ID that does
not match the others. This ensures that dual-ported disks cannot be
managed (and possibly corrupted) by two systems at the same time.
If you are sure that the dynamic disk group is not in use by another
host, you can clear the host IDs and import the dynamic disk group
by selecting the Clear host ID option.
