[rhn-users] Issue with SAN

[CIRIL IGNATIOUS T]

Hi Kumaresh
 
You need to disable the write cache.Then only the updates of a file will 
be reflected to the OS in the servers.
This can be done  from the SAN Storage management software .Also while 
making the LUN make the write policy as write through so that the write 
will be simultaneous in the cache as well as in the disks.

Regards

Ciril
