Hi all
We recently implemented 2 EMC VTL's (DL4200) in our environment. We did quite a bit of remediation work prior to getting hooking up the VTL which included updating the HBA drivers/firmware (driver is 9.1.7.18), updated TSM to 5.4.5.1 (on windows server 2003 SP2), ran new fiber cables into a new fiber switch (EMC DCX switch) and what not.
We still have our physical library connected too.
Since all this, i have been getting lots of i/o write errors on both the Virtual tapes (drives emulate 3592 JIA drives with compression enabled) and the physical tapes (LTO2 drives and tapes)
I can see in the TSM activity log the piles of write and read errors, and where it knocks the tapes into readonly mode, and i usually just go in and mark them readw.
Now sometimes, i do see corresponding ql2300 errors in my windows event viewer, but not all the time.
I have no clue where i need to start here. I am using the recommended HBA drivers, i am at a stable version of TSM.
I will probably open a call with both IBM, and EMC to see what we can track down, but i was wondering if anyone here may have some hints on what to look at.
thanks
