Trying to access 191 give DMSLIO109S

Bertram Moshier All Messages By This Member #5759 Hello, I'm getting DMSLIO109S when trying to access my 191 mini-disk.? It is a 3380 (the entire drive 000 to 886).? How large of a mini-disk does VM/CE support for 3380 DASD? Thank you.
Jeff Henry All Messages By This Member #5761 If I recall correctly, a 3380 only has 885 cylinders, not 886. (Unless you're using 'E' or 'K' models, but I'm not sure if VM/CE supports those.) toggle quoted message Show quoted text On Sun, May 19, 2024 at 7:18?PM Bertram Moshier via <herc370390vm=[email protected]> wrote: Hello, I'm getting DMSLIO109S when trying to access my 191 mini-disk.?

You can create a mini-disk as large as the DASD but, from my quick test, the maximum number of 800 blocks for a mini-disk on a 3380 seems to be 65340, which corresponds to 121 cylinders. In other words, even if you CMS format your mini-disk for a number of cylinders bigger than 121, there won't be more than 65340 blocks total anyway. BTW, when defining a CMS mini-disk, I recommend you to avoid cylinder 0 and start at cylinder 1. Cheers, René FERLAND, Montréal
Dave Wade All Messages By This Member #5764 开云体育 Bertram, This is why I never bother with large disks. CMS Minidisks are limited in size by the CMS 800-byte file system. You get a maximum of just under 64k 800 byte blocks per disk which is 115 cylinders of 3350. There are similar limits on the number of records in a file and the size of a file. Using cylinder 0 for a minidisk isn’t a good idea as CMS format then overwrites the disk label, which can result in a disk that isn’t mountable.
