in the format cUtXdYsZ, corresponding to the device name of the enclosure.
Note
The device name of the enclosure corresponding to the LU might vary before
and after installing HDLM. Make sure that you perform step 1 to check the
correspondence between the device name of the enclosure and the LU.
If the
vxdisk command displays the value of HDevName (cUtXdY) output by the
dlnkmgr command's view -path operation, the HDLM device is recognized
by VxVM. Go to step 2. If the
vxdisk command does not display the value of
HDevName (cUtXdY) output by the dlnkmgr command's view -path
operation, the HDLM device is not recognized by VxVM. In this case, perform
step 2, then re-execute step 1 to make sure that the HDLM device is recognized.
2. Execute the
vxdmpadm command for the devices displayed by the vxdisk
command to make sure that only the HDLM devices are
ENABLED.
To check whether the HDLM devices are
ENABLED, see the value of HDevName
(cUtXdY) output by the dlnkmgr command's view -path operation. Also,
make sure that all non-HDLM devices are removed from VxVM management and
not displayed.
The following shows an example of executing the command:
Note
The load balancing and failover functions will not work normally if the
vxdmpadm command outputs non- HDLM devices (devices that are not
displayed for
HDevName of the dlnkmgr command's view -path
operation), and if
STATE is ENABLED. Therefore, non-HDLM devices must
