- Non-destructive testing. Testing of the disks for SCSI-3 persistent reservations occurs in a non-destructive way; that is, there is only testing for reads, not writes. May be used with -m, -f, or -g options.
- Testing of the return value of SCSI TEST UNIT (TUR) command under SCSI-3 reservations. A warning is printed on failure of TUR testing. May be used with -m, -f, or -g options.
- Manual testing. This is the default option; that is, if no options are specified, the utility carries out the test suite in manual operation. The utility prompts for system names and device paths.
- -f filename
- Test the disks listed in filename. This is a batch test operation. All disks specified in the file are tested one by one. The format of the file is:Node1Name DevicePath Node2Name DevicePathEXAMPLES: (Note that the format of DevicePath varies by operating system.) For Solaris, if node SYSA and node SYSB have two shared disks, and the disks are seen as having DevicePath /dev/rdsk/c2t2d1s2 and /dev/rdsk/c3t2d1s2 on SYSA, and /dev/rdsk/c3t2d1s2 and /dev/rdsk/c3t2d2s2 on SYSB, the file filename contains:SYSA /dev/rdsk/c2t2d1s2 SYSB /dev/rdsk/c3t2d1s2SYSA /dev/rdsk/c3t2d1s2 SYSB /dev/rdsk/c3t2d2s2For HP-UX, if node SYSA and node SYSB have two shared disks, and the disks are seen as having DevicePath /dev/rdsk/c2t2d1 and /dev/rdsk/c3t2d1 on SYSA, and /dev/rdsk/c3t2d1 and /dev/rdsk/c3t2d2 on SYSB, the file filename contains:SYSA /dev/rdsk/c2t2d1 SYSB /dev/rdsk/c3t2d1SYSA /dev/rdsk/c3t2d1 SYSB /dev/rdsk/c3t2d2For AIX, if node SYSA and node SYSB have two shared disks, and the disks are seen as having DevicePath /dev/rhdisk70 and /dev/rhdisk75 on SYSA, and /dev/rhdisk60 and /dev/rhdisk65 on SYSB, the file filename contains:SYSA /dev/rhdisk70 SYSB /dev/rhdisk60SYSA /dev/rhdisk75 SYSB /dev/rhdisk65For Linux, if node SYSA and node SYSB have two shared disks, and the disks are seen as having DevicePath /dev/sdw and /dev/sdx on SYSA, and /dev/sdy and /dev/sdz on SYSB, the file filename contains:SYSA /dev/sdw SYSB /dev/sdySYSA /dev/sdx SYSB /dev/sdz
- -c coordinator_dg
- Tests disks in a disk group for coordinator disk functionality only. Testing does not include read/write testing and is not suitable for disks to be used for data.
- -g diskgroup
- Test all disks in the diskgroup. This option requires that Veritas Volume Manager is installed and running. A test disk group needs to be set up, with all disks to be tested contained within that group. Dynamic Multipathing (DMP) is tested with this option; that is, disks contained in the test disk group configured with DMP are tested for SCSI-3 compatibility.
- Use DMP devices for testing. This option may be used with -g or -c options. With this option, the script picks the DMP paths for disks in the disk group.
- Use raw devices for testing. This option may be used with -g or -c options. With this option, the script picks the raw paths for disks in the disk group.
- Use non-secure communication. By default, vxfentsthdw makes use of ssh and scp to communicate with nodes. When this option is specified, vxfentsthdw will use rsh and rcp for communication.
- -p utilpath
- Use utilpath as the path for VxFEN utilities used by vxfentsthdw. By default, vxfentsthdw will attempt to use vxfenadm from /sbin and vxfendd from /opt/VRTSvcs/vxfen/bin directories. These paths can be overridden to the utilpath specified with this option. This is useful when vxfentsthdw is used to test hardware on nodes that do not have the VRTSvxfen package installed. vxfentsthdw checks if the necessary utilities are available at their default paths. If not, it attempts to copy these utilities from the path where vxfentsthdw is being run to the specified tools directory. If this option is not specified, vxfentsthdw will attempt to copy the utilities to their default paths if they are not found on the target nodes.
