Cleaning the Control Station on VNX

Cleaning the Control Station on VNX

 

ssh into control station (IP noted on storage manual)

 

Check to see if there’s any stale tasks

cd /nas/tasks (only primary control station has this filesystem)

ls | wc -l

 

*should be normal to see single to double digits… 

 

Remove any stale tasks

rm -rf *_status

rm -rf *_pipe

 

check back the stale task status by another command of

ls | wc -l

 

to see the failover/failback status

/nasmcd/sbin/getreason

10 – slot_0 primary control station (slot_0 should be always primary, if else, login to slot_1 primary and reboot)

 0 – slot_1 reset

 5 – slot_2 contacted

 5 – slot_3 contacted

 

bring back to the primary node (as recommended)

login to slot_1 primary by command

su – nasadmin

reboot

 

Do not reboot from both primary and secondary control station at once! it will cause serious damage!

 

*wait for full boot up on each side and check status by getreason commands
