Subject: 3390 mod 9 Multivolume SAS Dataset ?Requires ESDS Implies No EXCP
? 213-B8
Content-Type: text/plain
I maintain a dataset in version 6 of SAS. SMS-managed disk-format SAS
libraries appear limited to 5 volumes. We are close to filling our current
disks and are attempting to replace them with (STK SVA emulated) 3390 mod
9's. The dataset will appear to the OS as a single dataset spanning 5
packs.
Our current dataset is allocated:
ALLOC USED EX DSORG -DCB ATTRIBUTES-
49935 49935 1 PS FS 27648 27648
49935 49935 1 PS FS 27648 27648

Our systems folks tell us that to allocate a single dataset filling an
entire 3390-9, we need to use extended sequential datasets. The explanation
is something about exceeding 65K tracks. While this allows us to allocate
the full five volume (emulated) 3390-9 dataset we want, writing it in SAS
(even reading it) generates an error: 213-B8: "An OPEN was attempted against
an extended
sequential data set with a DCB which specified EXCP.
EXCP is not supported for extended sequential data sets.
I expressed the problem badly to SI and got a bad answer. Before I try
again, I would like to hear from anyone who has tried to allocate an entire
3390 mod 9 to a single SAS library. Has anyone succeeded at this?
