Running an Application Outside the Global Cluster
How to Take a Solaris Volume Manager Metaset From Nodes Booted in
Use this procedure to run an application outside the global cluster for
Determine if the quorum device is used in the Solaris Volume Manager
metaset, and determine if the quorum device uses SCSI2 or SCSI3
phys-schost# clquorum show
If the quorum device is in the Solaris Volume Manager metaset, add a new
quorum device which is not part of the metaset to be taken later in noncluster
phys-schost# clquorum add did
Remove the old quorum device.
phys-schost# clquorum remove did
If the quorum device uses a SCSI2 reservation, scrub the SCSI2 reservation
from the old quorum and verify that no SCSI2 reservations remain.
The following command finds the Persistent Group Reservation Emulation
(PGRE) keys. If there are no keys on the disk, an errno=22
message is displayed.
# /usr/cluster/lib/sc/pgre -c pgre_inkeys -d /dev/did/rdsk/dids2
After you locate the keys, scrub the PGRE keys.
# /usr/cluster/lib/sc/pgre -c pgre_scrub -d /dev/did/rdsk/dids2
If you scrub the active quorum device keys from the disk, the cluster will
panic on the next reconfiguration with a Lost operational
Evacuate the global-cluster node that you want to boot in noncluster
phys-schost# clresourcegroup evacuate -n target-node
Take offline any resource group or resource groups that contain
HAStoragePlus resources and contain devices or file systems affected by the
metaset that you want to later take in noncluster mode.
phys-schost# clresourcegroup offline resource-group
Disable all the resources in the resource groups that you took
phys-schost# clresource disable resource
Unmanage the resource groups.
phys-schost# clresourcegroup unmanage resource-group
Take offline the corresponding device group or device groups.
phys-schost# cldevicegroup offline device-group
Disable the device group or device groups.
phys-schost# cldevicegroup disable device-group
Boot the passive node into noncluster mode.
phys-schost# shutdown -g0 -i0 -y
ok> boot -x
Verify that the boot process has been completed on the passive node before
phys-schost# svcs -x
Determine if any SCSI3 reservations exist on the disks in the
Run the following command on all disks in the metasets.
phys-schost# /usr/cluster/lib/sc/scsi -c inkeys -d /dev/did/rdsk/dids2
If any SCSI3 reservations exist on the disks, scrub them.
phys-schost# /usr/cluster/lib/sc/scsi -c scrub -d /dev/did/rdsk/dids2
Take the metaset on the evacuated node.
phys-schost# metaset -s name -C take -f
Mount the file system or file systems that contain the defined device on
phys-schost# mount device mountpoint
Start the application and perform the desired test. After finishing the
test, stop the application.
Reboot the node and wait until the boot process has ended.
Bring online the device group or device groups.
phys-schost# cldevicegroup online -e device-group
Start the resource group or resource groups.
phys-schost# clresourcegroup online -eM resource-group
