When faulty hardware is narrowed down to an IOC, the root cause may actually be the MICs installed on the IOC.

If a MIC is at fault and causing the IOC to fail, we will typically see the following messages:

Feb 22 01:00:03 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:04:31 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:08:58 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:13:26 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:27:45 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:32:15 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:36:43 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Feb 22 01:45:36 srx-abc123 node0.fpc2 cmic_vsc8248_init_by_eeprom: CMIC(2/0) ------NOT all vsc8248s is ready.

Reseat the IOC and the MIC. If the messages return, the MIC is faulty.

CMIC(#/#) refers to the FPC number, and then the PIC number. The MICs are numbered differently. MIC0 covers PIC0 and PIC1. MIC1 covers PIC2 and PIC3.

For example:

CMIC(2/0) = FPC2 MIC0

CMIC(2/1) = FPC2 MIC0

CMIC(2/2) = FPC2 MIC1

CMIC(2/3) = FPC2 MIC1
