After Activating the LPAR (Starting) to boot via Suse 12SP4 installed DVD (See Uploading a new OS ISO to VIOS Library and Add Virtual Optical Media to LPAR with desired OS ISO image), we can install OS using:
- After existing "System Management Service" via grub choose option of "Installation".
- You may have to press up-down arrow to get grub menu
- Careful avoid left-right arrow.
- In case of "Virtual Fiber Channel" based root disk at this point, we can start seeing WWN number on storage or FC switch. We should be able to see same no. of WWN as no. of virtual FC ports created (Assuming all physical FC are connected to SAN switch / storage).
- We can go to vHMC -> LPAR -> Virtual Storage -> "Virtual Fibre Channel" and see WWN under "WWPN" column.
- If storage was not mapped so far, we can add appropriate size root disk at this point.
- Typically at storage level Add host, Create LUN, Assign LUN to host
- In DHCP based environment with direct Internet, LPAR can get DHCP IP and then installer might update itself over Internet before starting.
- We can abort and skip this update
- In the text based installer proceed as follows:
- Leave language as "English" and Keyboard Layout as "English (US)"
- Agree to license (Alt+A). Go Next (Alt+N)
- Skip Registration
- On "Add On Products" go to Next
- On "Partitioning" Screen go to expert partitioner
- In case of FC based storag, first go to System View -> linux -> Configure and enable multipath. This way you can get a multipath device for OS installation instead of installing it on /dev/sda, /dev/sdb, etc.
- In case of FC, we may have to deactivate / shutdown LPAR with immediate option. Then reactivate it with "System Management Services" for FC based disk to be visible for OS installation.
- Configure partition as per requirement. Go to System View -> hard-disk. Add or Delete partition as per requirement.
- if warned about not having separate /boot, pay attention. Small /boot is required, rest all can be lvm / ext4 etc.
- Select appropriate timezone
- If required configure NTP
- Create user account (eg admin1), if required. You can also enable sudo access for this account as per requirement. Same password will get configured as root password.
- On Software selection page go to change. In Change select software. Change filter from "Search" to "Pattern" (Down arrow key). Then toggle (Space-bar) SAP-Application pattern to install all packages related to SAP
- Proceed with OS installation
- After OS installation we can login with root / norma-user (Eg admin1).
- Disable firewalld via below to enable SSH access to the LPAR
- systemctl stop SuSEFirewall2
- systemctl stop SuSEFirewall2
- Disable firewalld via below to enable SSH access to the LPAR
