HP XP RAID Manager Software - Manual (Page 180)

to avoid such problems is to transport to another host outside the cluster, but this enforces to set
up a backup server, so RAID Manager supports a facility to put back the signature as a second
way.
The signature can be changed by using the dumpcfg.exe command attached to Windows
resource kits, but if the S-VOL is created with the Noread option and the system is rebooted, then
the dumpcfg.exe command will fail to change the signature, because the system does not know
the signature and volume layout information for S-VOL.
RAID Manager adopts the following way with this point in view:
•
You must save the signature and volume layout information to the system disk by using the
inqraid -gvinf
command, after an S-VOL has set the signature and new partition by the
Windows disk management.
•
You can put back the signature by setting the signature and volume layout information to an
S-VOL that was saved to the system disk by using the inqraid -svinf command, after
splitting the S-VOL. If the S-VOL is created with the Noread option and the system is rebooted,
then the system can not create a device object (\Device\HarddiskVolume#) and Volume{guid}
for S-VOL, but the -svinf option will create a Device object (\Device\HarddiskVolume#)
and Volume{guid} without using the Windows disk management.
NOTE: The Cluster Disk Driver does not allow using the Noread volume as [Device is not ready]
at the boot time, since the Cluster Disk Driver is a Non-Plug and Play Driver. Verify this situation
using the inqraid command as follows:
inqraid $Phy -CLI
DEVICE_FILE PORT SERIAL LDEV CTG H/M/12 SSID R:Group PRODUCT_ID
Harddisk0 - - - - - - - -
Harddisk1 - - - - - - - -
In this case, do the following to disable the Cluster Disk Driver:
1.
In the Computer Management window, double-click System Tools, and then click Device
Manager.
2. On the View menu, click Show Hidden Devices. Non-Plug and Play Drivers appear in the list
in the right pane.
3. Open Non-Plug and Play Drivers, right-click Cluster Disk, and then click Disable. When
prompted to confirm whether to disable the cluster disk, click Yes. When prompted to restart
the computer, click Yes.
4. Verify that you can see the Noread volume using inqraid command as follows.
inqraid $Phy -CLI
DEVICE_FILE PORT SERIAL LDEV CTG H/M/12 SSID R:Group PRODUCT_ID
Harddisk0 CL2-K 61456 194 - s/S/ss 0004 1:01-10 OPEN-3
Harddisk1 CL2-K 61456 256 - s/S/ss 0005 1:01-11 OPEN-3
5. After starting up RAID Manager and splitting the S-VOL, put back the signature by using the
inqraid -svinf
command.
6. Again, in the Computer Management window, enable the Cluster Disk Driver, and restart the
computer.
