HP 316095-B21 - StorageWorks Edge Switch 2/24 Release Note page 26

Changing or removing the principal switch of a persisted fabric causes two
fabrics to be displayed
Fabrics are identified by the WWN of the principal switch. If a new principal switch is
selected (either manually, or because the current principal switch is removed from the
fabric), the fabric is reidentified by the WWN of the new principal switch.
If the principal switch of a persisted fabric is changed or removed, two fabrics are
displayed with identical switches, with the two fabrics identified by the former and
the new principal switch WWN. The persisted fabric indicates all switches have been
removed from fabric (red circle with minus sign) and all switch connections disabled
(yellow dashed lines). The new fabric is not persisted.
Similarly, if the principal switch of a persisted fabric is removed from the fabric (ISLs
removed or blocked) but still powered up and managed by HAFM, two fabrics are
displayed with identical switches, with the two fabrics identified by the former and the
new principal switch WWN. The persisted fabric indicates all switches except the former
principal switch have been removed from fabric (red circle with minus sign) and all
switch connections disabled (yellow dashed lines). The new fabric is not persisted.
Workaround
Unpersist the former fabric, and persist the new fabric.
Removing a Port Fencing Threshold Policy may not occur as expected under
specific conditions
Under specific conditions, a Port Fencing Threshold Policy may remain active even if the
user has removed it. This occurs when you are in the same Port Fencing configuration
session:
1. A particular Port Fencing Threshold Policy is not currently applied to any switch.
2. The same Port Fencing Threshold Policy is applied to switch port(s).
3. The same Port Fencing Threshold Policy is selected in the ISL Threshold table (left
panel), and Remove is clicked in order to remove this policy.
4. The Port Fencing configuration session is completed (by clicking OK).
Under these conditions, the Port Fencing Threshold Policy is not successfully removed and
is active on the switch ports where the policy was applied.
Workaround
This can be corrected by repeating the selection of the Port Fencing Threshold Policy
in the ISL Threshold table (left panel), by clicking Remove, and then clicking OK. The
Port Fencing Threshold Policy will then be removed correctly. This can be avoided by
also selecting the Port Fencing Threshold Policy on the switch ports where it was applied
(right panel), and removing the policy from the switch port(s), before completing the
session (step 4 above).
