/sapmnt/SID directory structure for SAP High Availability

[former_member189780]

Hi

We are in the middle of building new SAP landscape for fail over environment.

One of the application server would be in DMZ zone and other application server would be in Internal zone. We tried but we

are not able to make NFS for /sapmnt/SID work in DMZ zone.

Someone suggested us to copy the /samnt/SID in both Internal and DMZ zone. It mean, whenever

we have to make any changes in profiles or upgrade kernel or upgrade Patches, we need to make the

changes in both DMZ and Internal zone or to copy the /sapmnt/SID manually in both zone.

Not sure if this is the right approach to copy /sapmnt/SID in internal and DMZ zone?

Any suggestion would be much appropriated.

Thanks

Hi,

One of the best ways is to use IBM Power HA solution if you have AIX servers. Using Power HA you are going to have  a shared sapmnt/SID among 3 nodes.  Also if you have Oracle RAC you can use ASM to share sapmnt/SID as a solution for high availability.

Hi Amarjit,

Why you want to try to have one server in DMZ and other not. There are chances of having issues. Keep all the server of one SID in one zone.

consider cluster storage feature. e.g. Red Hat Resilient Storage and others.
