Hi, I have also been getting I/O errors on my LTO 3583 since I upgraded to V5.1.6.1 on Solaris. They generally seem to happen when the tape gets to about 95% capacity. They go to READONLY status but appear to be quite readable so I dont worry about them as they eventually expire and become scratches,
I did not see this problem at all under V4.2. I have 3 drives and a mixture of tape brands, but the problem appears to be completely random. Any ideas? Thanks Andrew Finlaison DBA University of Wollongong Phone 02 4221 3828 / 0413 041 722
