redhat cluster without fence device

hi all,

i have installed redhat el 5.1 on 2 x dl380 g5 with a shared storage (msa2012sa).

I have completed system configuration and multipath config. I even configured one lun to be use as quorum device.

i execute the following command to activate the device a quorum device.
mkqdisk /dev/mapper/mpath3p1

but when i start configure cluster, it ask about program for quorum device heuristic?

and then it ask to configure fence device. Can i skip this if i have quorom device. Configuring ILO for fencing device is not an option as we dont have enough network port allocate for it for the ILO.

Can this config works?

Re: redhat cluster without fence device

Hello,

Technically it does work. However, fencing is strongly recommended for data integrity. If ILO-fencing is not an option then you should look into imnplementing power fencing or/and SCSI reservation, etc ...

Re: redhat cluster without fence device

thanks all. I will proceed with iLo config for primary fencing and quorum as 2nd level of fencing.
