It doesn't seem to matter what size file, it is just a longer wait with a big file. I'm using dd to write a 1 gig file from /dev/zero to the filer. I've tried with both AIX 4.3.3 and 5.2.1 with similar results.

We do have AIX servers connected to F960. No issues. What size file are you trying to dd ? Thanks Deepak Soneji ----- Original Message ----- From: bill_link@dstoutput.com To: toasters@mathworks.com Sent: Monday, October 27, 2003 3:05 PM Subject: AIX write performance
Toasters,
I am having difficulty with large file writes to an f720 from any of my IBM hosts, if I start a large write with dd then try to do anything on the filer from that host it hangs until the write completes. From a different host access to the filer is near normal. I do not have this problem with linux boxes on the same network so it seems that the problem lies with AIX somehow. IBM has been sympathetic although not very helpful.
Any thoughts would be much appreciated.
