My problem is that, when planning a new TSM data space for Log, Database, or disk storage pool volume, I cannot figure out the maximum size I can allocate. I'm using AIX 4.3.3.ML9 with TSM 4.2.2.8. Step 1) Use the OS to create a Unix file system of the appropriate size and characteristics. The Unix "df -k" command (allegedly) tells me how big it is and how much space is in it: Filesystem 1024-blocks Free %Used Iused %Iused Mounted on /dev/kumquat 8781824 3008300 66% 18 1% /usr/local/kumquat Step 2) Format it. The following calculations are from "TSM Administrator's Reference". 3008300k/1024=2937m Rounding down to a multiple of 4mb gives you 2936m. Adding 1 for overhead gives you 2937m. However, specifying dsmfmt -m -db /usr/local/kumquat/db12 2937 It formats for a long time and then abends with message: Error writing file /usr/local/kumquat/db12, errno = 28 ...which means, not enough space. Where are my calculations going wrong? I can try to reduce the number a few mb at a time and figure this out by trial and error, but this takes literally DAYS of my time. So I usually guess at 98% and waste some space. How can I really calculate this?
