POST progress codes (checkpoints)

When you turn on the blade server, the power-on self-test (POST) performs a series of tests to check the operation of the blade server components. Use the management module to view progress codes that offer information about the stages involved in powering on and performing an initial program load (IPL).

Progress codes do not indicate an error, although in some cases, the blade server can pause indefinitely (hang). Progress codes for blade servers are 9-word, 8-digit hexadecimal numbers that start with C and D.

Checkpoints are generated by various components. The baseboard management controller (BMC) service processor and the partitioning firmware are key contributors. The service processor provides additional isolation procedure codes for troubleshooting.

A checkpoint might have an associated location code as part of the message. The location code provides information that identifies the failing component when there is a hang condition.

Notes:

For checkpoints with no associated location code, see Light path diagnostics to identify the failing component when there is a hang condition.
For checkpoints with location codes, see Location codes to identify the failing component when there is a hang condition.
For eight-digit codes not listed here, see Checkout procedure for information.

The management module can display the most recent 32 SRCs and time stamps. Manually refresh the list to update it.

Select Blade Service Data > blade_name in the management module to see a list of the 32 most recent SRCs.
