Maximum volume size (disk)?

[adams]

Hi there!

We use TSM 5.4 on a windows Server 2003, together with a tape library and an external storage device. On the latter one, I want to create a volume with a capacity of 2000 GiB:

DEFINE STGPOOL MY_POOL DISK
DEFINE VOLUME MY_POOL F:\DISK.IMG FORMATSIZE=2048000

This results in an error from TSM:

ANR2017I Administrator ADMIN issued command: DEFINE VOLUME MY_POOL F:\DISK.IMG FORMATSIZE=2048000 (SESSION: 12810)
ANR0984I Process 10 for DEFINE VOLUME started in the BACKGROUND at 11:51:11. (SESSION: 12810, PROCESS: 10)
ANR2491I Volume Creation Process starting for F:\DISK.IMG, Process Id 10. (SESSION: 12810, PROCESS: 10)
ANR4945E DEFINE VOLUME:The volume named F:\DISK.IMG is larger than is allowed for a volume on your system. (SESSION: 12810, PROCESS: 10)
ANR0986I Process 10 for DEFINE VOLUME running in the BACKGROUND processed 1 items for a total of 2,147,483,648,000 bytes with a completion state of FAILURE at 11:51:11. (SESSION: 12810, PROCESS: 10)

The file size limit on NTFS should be something around 16 TiB since Windows XP, also the created file has the size of 2147483648000 Bytes, which are exactly 2048000 MiB aka 2000 GiB.

Does TSM use an internal file size limit? Or what may be the problem here?

Thanks in advance

do you have enough space to handle 2 Tb on F:\ ?

Yes, I do. The file created has 2000 GiB which still leaves more than 30 GiB unoccupied. I don't have enough for 2 TiB (2048 GiB) though, but 2000 GiB are fine. I manually created files larger than this (like the maximum on this storage device around 2030 GiB).

Thanks

Try creating a 1.5 TB and see what happens. Maybe a Windows issue.

I tried different sizes, close to 2000 GiB, it worked with 2000000 MiB (~1953 GiB). I don't think this is a windows bug, as I can create bigger files than that, maybe a TSM bug?

Thanks for the input!

As of TSM version 5.4 the internal limitation is 2008000 MB. See APAR IC54759: ANR4945E ERROR REPORTS THE DISK VOLUME SIZE IS LARGER THAN ALLOWED AFTER DEFINE VOLUME CREATES THE FILE ON THE OS. Regards. Wim.

Thank you very much, now I know at least the limit and can work with this. Also thanks for pointing out directly the APAR.
