After the server hardware crashed and we had a chance to upgrade to VMWare ESXi 6.5. However after various steps to recover all the VMs, when we tried to start S4, it should license check error

We know that the license check actually depends on where the ASCS instance runs, however when we check the ASCS instance and it was not running at all!

During SAP installation the ASCS was installed in the same VM as Hana DB, so we tried to start ASCS, but failed:

SharkS4HDB:s4aadm 18> startsap ASCS00
 Cannot find startdb, DB startup failed

please send the tracefile /home/s4aadm/startsap.trc to support
