MC/S guard prob~~~~~~

[Chi Yi Lee]

Hi

i have three servers: act1, act2, and stand.
Two packages are pkg1 and pkg2.

pkg1 is connect to act1
pkg2 is connect to act2

if either server fail, pkg will switch to server stand.

What I want to do is, there are few lvols in pkg1 and pkg2 that I need them to appear in all the servers. Right now, only one server can see the packages and mount devices.

would this be possible?

set them up as NFS mountable, using hte HA NFS Toolkit as part of your package, this will allow the server running the package to export the file system, and allow them to be mounted remotley, using the relocatable ip address/hostname.

Hi,

NFS is the way to go but I try to avoid NFS as much as possible.

If there isn't any other way, then you will have to use NFS toolkit for Serviceguard otherwise managing it manually can be quite painful.

Look at the following document for more information. There are some nice examples given. In fact I used the two server cross-mount example to build a 5-node NFS cluster.

Don't be alarmed if the systems act strangely (commands hanging etc.,) during the failover.
