VxVM vxdisk ERROR V-5-1-684 IPC failure: Configuration daemon is not accessible
```
The issue occurs due to incompatibility between the RHEL kernel version 5.14.0-427.28.1 and InfoScale version 8.0.
To resolve the issue, the below options can be explored:
If there are plans to use the upgraded kernel version, then upgrade InfoScale to version 8.0.2 with IS 8.0.2 Update 3 on RHEL9 Platform (infoscale-rhel9_x86_64-Patch-8.0.2.2200), which supports RHEL kernel 5.14.0-427.28.1.
If upgrading InfoScale is not feasible, downgrade the RHEL kernel to a version that is compatible with InfoScale 8.0.
