VRTX - Performing a racadm racresetcfg may cause SPERC-E to enter into safe mode.


Performing a racadm racresetcfg may cause SPERC-E to enter into safe mode. This behavior may be seen with a VRTX External JBOD solution consisting of the following components:

  • VRTX - CMC 2.1
  • Dual SPERC-E in Fault Tolerance Mode
  • Single or Dual MD 1200/1220 Arrays

Additionally the following or similar critical error will be observed in the CMC GUI.

CTL96 RAID Controller in Chassis Slot 6 has entered safe mode with limited functionality due to Critical Error during boot - All drives will be hidden


Solution


The CMC resets the default value for SPERC-E to non-FT (Fault Tolerant). Access to data during this condition will not be impacted as a single SPERC-E will take over. However the SPERC-E configuration will no longer be in Fault Tolerant (FT) mode until it is back into FT mode.

Warning: A maintenance window for down time is required.


To correct this behavior, please perform the following steps to recover:


1. Power down all blade servers in the VRTX Chassis.
2. Place the SPERC-E controllers into FT Mode.
Chassis Overview >> Controllers >> Troubleshooting >> Enable Fault Tolerance >> Apply (Perform this for both SPERC-E in PCIe Slot 5 & 6).
3. Reboot VRTX Chassis.

The issue will be fixed in the CMC version 2.2 for PowerEdge VRTX .
