HI Guys,
I am doing a new HA implementation of SAP ABAP on Unix. We are using HANA as the database and it comes as an appliance with HA configured, so I am only concerned about the Application server HA. We will be using Solaris cluster to configure HA on ASCS. I have been trying to understand the filesystem/mounts layout for the ASCS instance. Hera are my questions:
1. Do I need to install HANA client on the ASCS or CI or both?
2. Do I create /sapmnt and /usr/sap/trans locally on ASCS and mount it on the CI? or vice versa?
3. Do I need to mount /usr/sap or /usr/sap/<SID> from CI to ASCS or vice versa? Or these mounts are separate & local to ASCS and CI?
4. Do I install SMD on ASCS too?
5. Do I install host agent on ASCS?
Can you please clarify the above questions and if possible, provide me the local filesystem layout and the NFS mounts that need to exist for the HA setup
I have referred all the installation guides with no clarity on these questions. Please do not refer me to those guides.
Thanks!

Hello,
All questions are answered by the installation guides.
Anyway:
The filesystem layout is at the installation guides. There is even a nice picture with arrows indicating what is mounted where.

Thank you Isaias for the quick response! Based on your response these are the mounts I would be creating:
ASCS:
/sapmnt
/usr/sap/trans
/usr/sap
/usr/sap/hostctrl
CI:
NFS: /sapmnt
NFS: /usr/sap/trans
/usr/sap
/usr/sap/hostctrl
/usr/sap/<SAPSID>/hdbclient
/usr/sap/<DAA_SID>
Is there anything else I need to be mounting from the CI to the ASCS?
Thanks!
Veera
