PROBLEM STATEMENT:
V5.7 Console Firmware has two versions of PALCode; for EV6 and EV67
CPU's. Updating SRM firmware loads the correct PALCode version.
The wrong PALcode can exist if you change CPU's from EV6 to EV67 or
from EV67 to EV6 without updating updating SRM firmware.
PROBLEM SYMPTOM:
Serious:
EV67 PALcode in an EV6 CPU - possible CPU hangs or other anomalies.
Not so serious:
EV6 Palcode in an EV67 CPU - a possible slight performance loss.
SOLUTION:
Ensure correct PALcode by updating SRM console firmware (V5.7-84 or
greater) after upgrading CPU's from EV6 to EV67 or after downgrading
CPU's from EV67 to EV6.
ADDITIONAL COMMENTS:
PALcode for EV6 is in the format of Vx.yy-z
PALcode for EV67 is in the format of Vx.yy-zzz
Verify PALcode format after updating SRM firmware:
>>> show pal
V5.8 console firmware (when available) will detect a PALCode/CPU
mismatch by issuing a warning at the console display and by logging
a warning in the console error log.
