vxfentsthdw options (continued)
When to useDescriptionvxfentsthdw option
For testing disks in coordinator
disk group.
See “Testing the coordinator
disk group using vxfentsthdw -c
option” on page 74.
Utility tests the coordinator disk
group prompting for systems
and devices, and reporting
success or failure.
-c
For testing a few disks or for
sampling disks in larger arrays.
See “Testing the shared disks
using the vxfentsthdw -m
option” on page 76.
Utility runs manually, in
interactive mode, prompting for
systems and devices, and
reporting success or failure.
May be used with -r and -t
options. -m is the default option.
-m
For testing several disks.
See “Testing the shared disks
listed in a file using the
vxfentsthdw -f option”
on page 78.
Utility tests system/device
combinations listed in a text file.
May be used with -r and -t
options.
-f filename
For testing many disks and
arrays of disks. Disk groups may
be temporarily created for
testing purposes and destroyed
(ungrouped) after testing.
See “Testing all the disks in a
disk group using the
vxfentsthdw -g option”
on page 78.
Utility tests all disk devices in a
specified disk group.
May be used with -r and -t
options.
-g disk_group
Testing the coordinator disk group using vxfentsthdw -c option
Use the vxfentsthdw utility to verify disks are configured to support I/O fencing.
In this procedure, the vxfentsthdw utility tests the three disks one disk at a time
from each node.
The procedure in this section uses the following disks for example:
■ From the node galaxy, the disks are /dev/vx/rdmp/c1t1d0,
/dev/vx/rdmp/c2t1d0, and /dev/vx/rdmp/c3t1d0.
■ From the node nebula, the same disks are seen as /dev/vx/rdmp/c4t1d0,
/dev/vx/rdmp/c5t1d0, and /dev/vx/rdmp/c6t1d0.
