Hi

just want to know, what the restrictions are for hostbased mirroring (lvm2) in a serviceguard linux cluster environment
(useing Redhat EHL4 Update 4, SG A11.16.07, EVA VCS 3028)

customer wants to build a 2 node cluster (proliants), each connected to EVA5K with dual pathes and 1km distance between each datacenter.

is "hostbased" mirroring supported in this way?

thx a lot for comments
-Walter

You may have paid support, please ask your Resourcing Engineer/Manager about the product purchase details and ask Redhat Online support.

Shalom,

This is fully supported as far as I remember. The HP-UX product is SG Metro or Continental cluster.

A fast pipe is essential to make this work.

This will be available with the new XDC or Extended Distance Clusters product coming out for Serviceguard on Linx sometetime within the next few months.

SG for Linux does NOT have a ContinentalClusters equivalent, an dthe MetroCluster equivalent is using CLX or Cluster Extensions for XP or EVA arrays,a dn dos NOT use host based mirroring
