Report Target Port Groups (HP Bridged)
216 SL150 Interface Reference Manual Julyl 2017
Target Port Group Descriptor Data Definitions:
PREF This bit indicates if the target port group is a preferred target port group.
0b indicates the target port group is not a preferred target port group.
1b indicates that the target port group is a preferred target port group.
Note – All ports in the Active/Optimized group are preferred
Asymmetric Access
State
This field contains the target port group’s current asymmetric access state.
The library supports the following Asymmetric Access States:
0h = Active/Optimized.
This state indicates that the ports in the group are fully operational.
3h = Unavailable.
This state indicates that the ports in the group are not available.
T_Sup The library returns a Transitioning Support bit of 0, indicating the Transitioning
asymmetric access state is not supported.
U_Sup 0 = The Unavailable asymmetric access state is not supported.
1 = The Unavailable asymmetric access state is supported.
S_Sup The library returns a Standby Support bit of 0, indicating the Standby
asymmetric access state is not supported.
AN_Sup The library returns an active/non-optimized support bit of 0, indicating the
Active/non-optimized asymmetric access state is not supported.
AO_Sup 0 = The Active/Optimized asymmetric access state is not supported.
1 = The Active/Optimized asymmetric access state is supported.
Target Port Group The target port group field contains an identification of the group.
00h = Target Port Group 0
01h = Target Port Group 1
Status Code The library returns a status code value of 2, indicating the target port group
asymmetric access state is altered by implicit asymmetrical logical unit access
behavior.
Target Port Group Count The target port count field indicates the number of target ports that are in the
target port group and the number of target port descriptors in the target port
group descriptor. The target port group count can range from a value of 1 to 2.
