Description


SPARC T3-1/Netra T3-1 systems may experience "hot removal of /SYS/PDB" errors and shut down.

Likelihood of Occurrence


This issue can occur in the following platforms:

SPARC Platform
  • SPARC T3-1 without System Firmware version 8.1.0.e (as delivered in patch 147315-03)
  • Netra T3-1 without System Firmware version 8.1.0.e (as delivered in patch 147319-03)

Note: This issue only occurs on the SPARC T3-1 and Netra T3-1 systems.

Possible Symptoms


If the described issue occurs, errors similar to the following will be seen in the event logs:
   Chassis   Action  major
Hot insertion of /SYS/PDB
Chassis Action minor
Inventory has been updated starting at node '/SYS'
Fault Fault critical
Fault detected at time = The suspect component:
/SYS has fault.component.missing with probability=100. Refer to
http://www.sun.com/msg/SPT-8000-J4 for details.
System Log minor
Host: Powered Off
Chassis Action major
Hot removal of /SYS/PDB

Workaround or Resolution


There is no workaround for this issue.

This issue is addressed in the following releases:
  • SPARC T3-1 with System Firmware version 8.1.0.e (as delivered in patch 147315-03) or later

Modification History

16-Sep-2011: Resolved Release

Internal Section: Comments:

The host was being powered off, causing a FRUID write of the power-off event:
May 25 11:32:14 bur415-23-sp dynafrud: dynafru_update_power_records:105:Wrote power records to /SYS/PDB

Causing the PDB to go absent:
2011-05-25/11:32:14 ereport.component.absent@/sys/pdb /SYS/PDB/PRSNT

During a FRUID write, the SEEPROM is unavailable for several ms. ILOM has protection against this:

1. The get_i2c_present() routine has protection against this by retrying 3 times in a row.
2. The poller, getting a state-change reading, will retry to see that the state-change still exists.

These effects multiply each other, so there are a total of 6 reads done. However, they are done without any delay in between, so it's possible that they could execute quite quickly. So it's possible, tho unlikely, that the FRUID writes (there are quite a few required) keep the FRUID unavailable at just the exact timing that all six retries fail to access the SEEPROM.

Specific Product and Platform choices have been added to this Sun Alert to conform with and enable MOS Hot Topics delivery.(for this doc: Solaris SPARC Operating System - GENERIC (All Platforms)
