The Dlmvxexclude Utility For Assisting Creation Of The Vxvm Configuration File - Hitachi XP P9500 User Manual

the dlmsetconf utility is executed before the logical device files of the
HDLM devices corresponding to the deleted LU are deleted, then the
format command might incorrectly display the logical device file name of
an HDLM device corresponding to the deleted LU, for the newly
recognized LU.
• When using SDS or SVM and executing the dlmsetconf utility after
making changes in the path configuration, you must not specify the -r
parameter. If you do so, the metadevices and volumes might be
unavailable.
• Executing the dlmsetconf utility with the -u parameter specified does not
update the unconf property in the HDLM driver configuration definition
file (/kernel/drv/dlmfdrv.conf) if no change is made to the HDLM-
managed devices. After the reconfiguration option is specified to restart
the host, the HDLM driver configuration definition file (/kernel/drv/
dlmfdrv.conf) that was updated takes effect in the system.
• If you want HDLM to manage a device that is not currently managing,
comment out the LDEV line (add a hash mark (#) at the beginning of the
line) of the definitions for the desired LU in the HDLM driver
unconfiguration definition file (/opt/DynamicLinkManager/config/
dlmfdrv.unconf), specify the reconfiguration option, and then restart the
host.
• When you specify that a device is, or is not, to be managed by HDLM, edit
the HDLM driver unconfiguration definition file (/opt/
DynamicLinkManager/config/dlmfdrv.unconf) to execute the
dlmsetconf utility with the -u option specified, and then restart the host.
• If the below message appears after you execute the dlmsetconf utility, it
means that the device ID could not be acquired from the SCSI driver. If
this happens, restart the host and then re-execute the dlmsetconf utility.
KAPL10237-E The property information (devid) on a device
(aa...aa) could not be collected.
aa...aa: sd or ssd device name
If the device ID cannot be acquired from the SCSI driver, refer to the bug
report for Bug ID 4897065 provided by SUNSOLVE(TM) ONLINE (http://

The dlmvxexclude Utility for Assisting Creation of the VxVM
Configuration File
This utility outputs the file (vxvm_exclude.txt) having the same format as
the VxVM management target exclusion file (/etc/vx/vxvm.exclude) that
matches the definition in the HDLM driver configuration definition file (/
kernel/drv/dlmfdrv.conf) to the directory specified by the -d parameter. If
the -d parameter is not specified, the dlmvxexclude utility for assisting
