• When the chdev command is used to set as defined, and then
reconfigure, an existing individual hdisk for which the attribute value has
not changed.
•
When deleting an existing hdisk
#
When an hdisk for which the attribute value has been defined is
reconfigured without being deleted, the set attribute value is carried over.
If the attribute value for individual hdisks needs to be changed, instead of
using this utility, execute the chdev command for the necessary hdisks.
Note that if the attribute value has been set for each hdisk, the set attribute
values will be applied.
Supplemental Information:
For HDLM 6.2, the default value for the hdisk reservation policy was set to
PR_exclusive. When the conditions listed in
Settings on page 3-84
to change the reservation policy to no_reserve, the chdev command had to
be executed for each hdisk.
In HDLM 6.3 or later, the default reservation policy values for multiple hdisks
can be changed simultaneously by executing the dlmchpdattr utility.
