Info
An issue has been identified on HPE StoreOnce Backup Systems where, after upgrading to software version 3.15.1 or later, the Catalyst Over Fibre Channel (CoFC) WWNN and WWPN values may change and access to fibre channel devices is lost.
This issue will only occur if the default values for any of the following HPE StoreOnce Catalyst Fibre Channel settings are changed, prior to upgrading from software version 3.13.x to version 3.15.1 or later:
