# sk179653 - Changes to the Security Gateway Module (SGM) ratio do not survive a reboot when two or more SGMs reboot at the same time: "ERROR: Chassis factors are NOT equal between chassis - Please Check Log"

## Symptoms

- * You set the SGM ratio with this gClish command:  

  `gclish> set chassis vsls sgm_ratio X`
* You rebooted two or more SGMs at the same time.

* After the reboot, the "`asg stat vs`" command shows this error:

  *ERROR: Chassis factors are NOT equal between chassis - Please Check Log*
* After the reboot, "`g_fw ctl get int fwha_mbs_vsls_chassis_sgm_ratio`" shows that the value of the kernel parameter has returned to 50:

  `[Expert@admin]# g_fw ctl get int fwha_mbs_vsls_chassis_sgm_ratio`  
  `
  -*- 6 blades: 1_01 1_02 1_03 2_01 2_02 2_03 -*-`  
  `
  fwha_mbs_vsls_chassis_sgm_ratio = 50`
* After the reboot, the new values are still present in the active database:

  `[Expert@admin]# grep -i "chassis:vsls:sgm_ratio" /config/active`  
  `
  chassis:vsls:sgm_ratio 50`

## Cause

The newly set configurations are not pushed during the booting sequence.

This **workaround** is available:  

1. Add the desired values to the *fwkern.conf* file manually to make sure the changes survive a reboot:  

   Run this command:  
   `g_update_conf_file $FWDIR/modules/fwkern.conf fwha_mbs_vsls_chassis_sgm_ratio=<Value_of_Kernel_Parameter>`  

   **Example** :  
   `g_update_conf_file $FWDIR/modules/fwkern.conf fwha_mbs_vsls_chassis_sgm_ratio=70`  

2. Confirm the changes:

`g_fw ctl get int fwha_mbs_vsls_chassis_sgm_ratio`
