Symptoms

XSCF is marked degraded due to a  SCF-8006-WP fault -

 *   XSCFU Status:Degraded;

Date: Oct 08 10:48:37 CDT 2014     Code: 40000000-faffc201-0101000200000000
   Status: Information            Occurred: Oct 08 10:48:35.448 CDT 2014
   FRU: /FIRMWARE,/XSCFU
   Msg: XSCF self diagnosis warning detection

   UUID: 10c5ce36-4a96-4c92-8122-8be40c93397b MSG-ID: SCF-8006-WP

Changes

 Issue occurs at login attempt on the XSCF, it may be reported that after a failed login attempt that the XSCF does not allow further logins for several hours.

Cause

Investigation of the XSCF OS messages logs may reveal these errors at the time of the fault code being produced -

Sep 18 06:59:47 ssm0174-lom sshd(pam_unix)[27091]: session opened for user xfadmin by (uid=0)
Sep 18 06:59:48 ssm0174-lom kernel: Eep. Trying to read_inode #3082 when it's already in state 2!

Note - this specific issue has been seen so far on XCP 1115, 1116 and 1117

Solution

Fault to be cleared (which requires a chassis power cycle on M3000/M4000/M5000) and the XSCF upgraded to XCP 1119 or XCP 1120.

XCP 1119 merely changes the fault to no longer degrade the XSCFU when encountering it

XCP 1120 has the final fix to JFFS to avoid the inode error completely
