Dear forum users,
Problem description: Sometime our UCS Chassis 5108 and both IOM are suddenly INACCESSIBLE. This happens frequently (Happend 5 times in just a month)
Temporary Solution: To unplug and re-plug Chassis power cords twice, then the Chassis back to normal
Once the Chassis is inaccessible state, below are what we witness on the Chassis:
- All the blades LEDs on chassis-1 shows amber lit
- 8 ports on IOM A and IOM B shows NO LED lit (Not even amber lit)
- Sudden increased in Fan speed on chassis-1
- FI ports which connected to Chassis-1, shows NO LED it
- Please find attached (Chassis-1_Fault.jpg) Fault message on chassis-1
We had tried the following:
- Tried re-sit the uplink cable
- Tried replacing the uplink cable, the port is still down
- Reboot FI
- Decommission the chassis-1
- Recommission the chassis-1
Below is our setup environment:
- 2x UCS 6248UP
- 2x UCS 5108
- 4x UCS 2208XP (2 IOM per chassis)
- 2x UCS B200 M2
- 5x UCS B250 M2
- Firmware 2.0(3b)
- Each IOM has 4 Uplink cables connect to FI
- Chassis Discovery Policy
1. Action (4 Links)
2. Link Grouping Preference (Port Channel)
We hope, someone should have experience with the same problem or have some advise to be shared.
Please let me know should you need any further details of the problem or other information.
