Hi HankD,  If the bin file load is complete you need not wait to use the system as the VTOC will continue in the background. If you need to write to a volume before the VTOC has completed then the system will VTOC the tracks you require before completing a write.  Steve
 I'm installing a new vMax with 950 drives. The bin file was loaded by noon today and it running the format on the drives. How can I tell where it's at in the formatting?
