Hi Gurus
For high availabilty ,our company is looking for HA solution.
We have 2 blade servers ,with fibre channels and 4 ethernet cards connected to a switch and to SAN storage .I want to know what are the procedures to do redhat clustering ,configure fibre channels ,switch and SAN.We have got RHEL4.0 license.If any1 can guide me to do this ,it will be very helpful .i have little idea about redhat cluster suite .but dont know how exaclty it will work .If any of u guys have done b4 ,pls let me know the procedure. [/b]

It all depends upon what service you want to put under HA. For example. web server (Apache) or mail server etc. Procedure to ha some time changes for example MySQL server clustering different than normal web server. So let us know

1) What service/server you want?

2) You want to setup Application/Service Failover or IP Load Balancing? Both are different but comes under HA

Let us know then we can guide you further

SAN use to store data from all server
Using an NFS-served Ext3 file system, or GFS you will able to deploy large pools of shared storage that can be accessed by multiple server or servers in cluster.

Three steps to attach SAN to Linux boxes
a) Configuring the fibre HBA (Host Bus Adapter)
b) Configuring the udev service to find the SAN Volume(
c) Configuring the fstab entries to mount the SAN Volume(

Run following command to configure RHEL cluster
It is not that hard. I recommend reading all docs loaded here
