changing vxfen scsi3_disk_policy from raw to dmp without outage

hi,

we have a setup to use scsi3_disk_policy=raw (/etc/vxfenmode) but it should be dmp

is is possible to update this without deporting the diskgroup resources ?

thanks in advance

 

  • if it is two node cluster.. on both node need to stop had service (hastop -local -force)  it may keep exisiting service online.. then stop the vxfen service on both node.. and edit the /etc/vxfenmode config file then start vxfen and hastart on both node... no need to change anything on fencing diskgroup.... 

    verfify the fencing policy using this command.. -- 'vxfenconfig -l'
