When configuring more than one storage devices using the same LocalVolume CR in PGT, only the first one will be added to generated policy.  

ZTP 4.11.z

100%

1. Deploy cluster via ZTP with 2 storage class devices added under the same LV CR:

2. Check generated policy

Generated policy contains only 1 storageClassDevice

Generated policy includes both storage devices

Workaround: use two LVs in PGT, each contains only 1 storage class device.
