remember CKD disks haven't been manufactured for decades, all being simulated on industry standard FBA devices ... originally 512 byte fixed block ... but industry moving to 4k byte fixed block. In between are 4k FBA that simulate 512 byte. https://en.wikipedia.org/wiki/Advanced_Format where you might have CKD simulated on 512 byte FBA simulated on 4096 byte FBA gets even more complex when RAID is layered over the top. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
