Opened: Aug 09, 2017

Severity: 3-Major

Symptoms

These symptoms can be seen on BIG-IP B2100 and B2150 blades. When the AOM resets itself unexpectedly, these types of symptoms can be observed: -- LED alarm light may be red. -- Messages may be logged to /var/log/ltm. Examples of typical messages: -- warning chmand[6890]: 012a0004:4: getLopReg Dev error: LopDev: sendLopCmd: Lopd status: 2 packet: action=1 obj_id=67 sub_obj=0 slot_id=ff result=0 len=3 crc=0 payload=28 8 4 (error code:0x0) -- err chmand[6890]: 012a0003:3: GET_STAT failure (status=0x2) page=0x28 reg=0x8 : File mgmtif/BourneMgmtIfSvc.cpp Line 282 -- notice chmand[6890]: 012a0005:5: Tmstat::updateMgmtIf: Lop error -- warning chmand[6890]: 012a0004:4: getLopReg Dev error: LopDev: sendLopCmd: Lopd status: 2 packet: action=1 obj_id=67 sub_obj=0 slot_id=ff result=0 len=3 crc=0 payload=1 0 2 (error code:0x0) -- err chmand[6890]: 012a0003:3: GET_MEDIA failure (status=0x2) page=0x1 reg=0x0 : File mgmtif/BourneMgmtIfSvc.cpp Line 376

Impact

These errors are effectively benign: -- The watchdog/reset feature of the AOM controller provides resilience to recover from unexpected fault conditions. -- The AOM re-initializes and comes back to proper operating state in the system. -- Production traffic is not affected.

Conditions

This may occur on BIG-IP B2100 and B2150 blades. Additional conditions under which this occurs are not well understood.
