New trace tags "sysuas*" added in kernel to trace zfcp sysfs unit add store events. Print the trace events under HBA with new record ID 6. The fields under this tag are WWPN, FCP LUN and return value of the device having issues. Example zfcpdbf output for unit add store events: Timestamp : 2026-02-02-10:50:02:474983 Area : HBA Subarea : 00 Level : 4 Exception : - CPU ID : 0003 Caller : 0x000001d89a86bd0e Record ID : 6 Tag : sysuas2 Description : sysuas2 HBA, Sysfs unit add store failure, unit add failed Request ID : 0x00000000ffffffff Request status : 0xffffffff FSF cmnd : 0xffffffff FSF sequence no: 0xffffffff WWPN : 0x500507680b26c449 LUN : 0x01d0000000000000 Return Value : 0xfffffff4 Timestamp : 2026-02-02-10:50:02:475037 Area : HBA Subarea : 00 Level : 4 Exception : - CPU ID : 0003 Caller : 0x000001d89a86bd0e Record ID : 6 Tag : sysuas2 Description : sysuas2 HBA, Sysfs unit add store failure, unit add failed Request ID : 0x00000000ffffffff Request status : 0xffffffff FSF cmnd : 0xffffffff FSF sequence no: 0xffffffff WWPN : 0x500507680b26c449 LUN : 0x01d1000000000000 Return Value : 0xfffffff4 Signed-off-by: Chinmaya Kajagar <chinmayk@linux.ibm.com> Signed-off-by: Jan Höppner <hoeppner@linux.ibm.com>
