7.3 dlmchpdattr Utility for Changing HDLM Default Settings

This utility changes the default value for the hdisk attribute.
By changing the default value, the attribute value set for an hdisk can be changed in

the following cases:

When a new hdisk is configured.
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

#

, and then reconfiguring it.

#

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 Table 3-21: Reservation Policy

Settings in 3.9 About the Reservation Policy are met, 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.
