Subject: | How to find out PVs preventing SSCAN from running? |

Hi,
We have an IOC doing ramps (1-D scan) using sscan record. It had been working properly in Debian 7 until recently we switched to RHEL8. When setting the EXSC field of the sscan record to 1, the scan didn't start as expected. The IOC reported:
----------------------------------------------
Starting new scan with unexpected faze ('SCAN_PENDING').
----------------------------------------------
The SMSG field or the sscan record read:
----------------------------------------------
Waiting for PV's to connect
----------------------------------------------
And the CPT field remained 0.
The sscan record has D01PV and P1PV associated with PVs also created in this IOC, both shown as connected, readable and writable from cainfo.
Is it possible to find out what PVs, or actually something else causing this problem?
Thanks for any comments.
Ji Li
