A user alarm cannot be created.
Error code:
SA_ERR_HPI_OUT_OF_SPACE
The DAT has reached the limit (50 by default) for the number of user alarms that can be active simultaneously.
Consider these options:
• Delete the oldest user alarm from the DAT
• Delete the most minor user alarm from the DAT
• Choose not to add the new user alarm
For information about configuring the number of user alarms, see Configuring HPI alarms on page 46.
Data cannot be added to the
MultiRecord area.
Error code:
SA_ERR_HPI_OUT_OF_SPACE
Neither new records nor new data for the existing PICMG MultiRecord area can be added directly to the FRU
data inventory for a module or a shelf. The OEM MultiRecord area can be updated directly. Instead, use one of
these two methods to update the MultiRecord area:
• Setting controls in the shelf resource
• Using a utility such as rsys-ipmitool to overwrite the existing image
