The scsimgr command output below shows the values of the tunables after the disks are opened or
re-opened - In other words after the attributes are reloaded.
Note the following:
• Now current values of the attributes are set based on the inheritance rules. Most importantly
these values correspond to the operational requirements outline earlier.
• disk0:
- The path_fail_secs attribute, is explicitly set for disk0. So the current value is unchanged.
It is not inherited from a higher level.
- disk0 does not match any of the 2 settable attribute scopes added. The default and
current values of load_bal_policy and max_q_depth attributes are inherited from the
global level.
• disk1:
- Default and current values of the path_fail_secs and load_bal_policy attributes are
inherited from the current value of corresponding attributes set at the settable attribute
scope covering devices with pid: ST3360LCB.
- The max_q_depth attribute is not explicitly set at the attribute scope covering disk1. It
inherits its default and current values from the global level.
• disk2:
- The default and current values of the max_q_depth attribute are inherited from the current
value of this attribute at the settable attribute scope covering devices with pid:
ST39103FC2.
- The path_fail_secs and load_bal_policy attributes are not explicitly set at a settable
attribute scope covering disk2. They inherit their current and default values from the
global level.
