Tsm server 6.2.5
TDP for vmware 6.4

I have the vmware data pool defined as a sequencial file pool, to facilitate 
migration.

However, last night the server claimed it was out of data storage space, but 
there is 18% of a 14 tb pool free.

I checked, and the only limit reached was maxscratch.

Is there a good way around this?

We want to migrate to server 7.x, but could not get an install failure resolved 
on RHEL 6.5 for server version 7.1.1.

I have increased maxscratch, but this cannot go on indefinitely.
