SAP Netweaver installation issue - Primary Application Server

[HemantVaswani]

I need to setup a fresh SAP S4 HANNA 2022 distributed system which comprises 3 servers HANA DB, ASCS and PAS.

Of three above,

the S4 HANA DB is up and running. Instance 02

ASCS is installed on instance 00. ABAP message port 3600 and internal port 3900

While installing the PAS server, I select the instance 01, message port 3601 and internal port 3901. However the PAS server installation is not getting completed. It is held up at 70%

I am using swpm tool for above installations

The pas server installation is stuck up at step where it is not able to test the start and stop the 01 instance.

My findings are

From PAS to ASCS , port 3600 is working ok

3601 and 3901 are saying connection refused

For above reasons, the disp+work service in sapcontrol command output shows YELLOW continuously

I have been trying to resolve the port issue for past several days with none useful result

Please share *sapinst* files.

Also, you can do ls -ltr to view the latest modified files in descending order instead of plain ls command.

Hi SS, Refer to the SAP Note 2179550, while reaching the step of checking (using the sidadm user) the output of msmon pf=/sapmn/SID/profile/DEFAULT.PFL is showing status as "Starting", kindly suggest.

[S_Sriram]

Hi Hemant,

Could you share the OS details on PAS and DB?

Regards

SS

[HemantVaswani]

Hi Sriram,

HANA DB Host and PAS host both having following OS :

Operating System: SUSE Linux Enterprise Server 15 SP4

Kernel: Linux 5.14.21-150400.24.100-default

Thanks, Hemant

[S_Sriram]

Hi Hemant

1. Could you share the log file /tmp/sapinst_instdir/s4hana2022/core/hdn/install/distributed/abap/app1

2. From PAS to DB instance network connectivity correct? is this any firewall blocking? In one of the log connectivity from PAS to DB instance getting time out.

3. Can the PAS system restart and retry the same installation phase?

Regards

SS

[HemantVaswani]

Hi SS, pl find update for each of the query above.

1. pl find the logs here

sapinst-log.txt

sapinst-dev-log.txt

2. at OS level, i am able to find normal ping response from PAS to DB host

3. I have tried earlier on 7th Jan with no luck,

Thanks

Hemant

[manojsomkuwar]

Hi, Ideally PAS will not have Message Server Ports 36** and 39** running as ASCS Instance is separately available.

Could you please share the error screenshot and also the logs.
