Volume restrictions

When the volume concerned has been set as a protected volume using the
raidvchkset command, the following restrictions are placed upon it:
• The setting with the raidvchkset –vg svd or raidvchkset –vg idb can be
perform without using the license key for Data Retention, however, the
setting cannot be released by Navigator 2. In regard to an LU for which
the setting has been made using the raidvchkset –vg svd or raidvchkset
–vg idb, operations such as deleting and formatting of it are restricted.
To release the setting, issue the raidvchkset –vg command.
• When setting the data protection for a UNIX file system volume, make
the volume concerned unmounted, and then mount it as a read-only
volume to use it.
For a Windows Server file system, you have to use " –x mount" and "-x
umount" option of CCI commands with above procedures.
For a Windows 2000 file system volume, a read-only volume is not
recognized correctly.
• When changing a configuration of the LVM including a protected
volume, the volume concerned must be temporarily placed in the status
in which the check on it is inhibited by the raidvchkset –vg command.
Place the volume again in the status in which it is checked when the
LVM configuration change is completed.
• There may be a case where a volume to which the data protection is
applied cannot be used as a resource of the HA cluster software (such
as the MSCS). This is because the HA cluster software (such as the
MSCS) writes management information in the management area
periodically in order to check propriety of the resource.
• When setting a volume being used by Windows 2000 or Windows
Server as a protected volume, the protection can be applied to a basic
disk only. When the protection is applied to a dynamic disk, the volume
is not recognized correctly.
• Some OS cannot be recognized LUNs over LUN#1, if LUN#0 will being
set to the "inv" as the attribute of the data protection, the reason is
that some HBA driver does not scan all LUNs on a port, if LUN#0 will be
invisible.
