Also what does len, max len and totalops stand grd = Global FIle Descriptor. Each one is an open chunk. Len = number of I/O operations waiting to access that chunk. Max Len is the maximum value of len since stats were last reset Total ops = Total number of I/O operations >for? Does a maxlen of 56 means that that is what longest queue was for >that vp. I seem to have 56 aio processes running judging by output of Yes. >onstat -g glo. The documentation says to look at this output to>determine if the number or aio requests waiting is growing.
