Error description

after setting the value using above command and after the
reboot, it suppose to set the value to 1, instead ioo
display it's value as
#ioo -o iodone_distr_disable
iodone_distr_disable = 0

similarly the tunable vmm_klock_mode:
#vmo -r -o vmm_klock_mode=1
after setting the value using above command and after the
reboot, it suppose to set the value to 1, instead vmo
display it's value as 0
#vmo -o vmm_klock_mode
vmm_klock_mode = 0

Local fix

  • The value of the tunable iodone_distr_disable is set to
the correct value inside the kernel, so no functional
issue.

Problem summary

  • If the customer changes the value of the iodone_distr_disable
ioo tunable to 1 and reboots, a value of 0 is incorrectly
reported.

Problem conclusion

  • Use the value of the kernel variable directly to set the
current value during initialization.

Temporary fix
