RE: cond wait: drcb_bqe problem

We are doing async HDR. Our network pipe from Austin to Denver is DS3 45 mbits/sec. The ping time is 33 ms. I didn't notice any L0, L1, or L2 at the time. Though I did see the logbf in the cond wait.

What is the ping time between the primary and the secondary? Since you are seeing the cond wait drcb_bqe, I'm assuming that you are doing async HDR. Are you also seeing L0, L1, or L2 waits when doing onstat -g ath? M.P. > > This problem has been reported to IBM Technical Support, but so far, no > solutions or recommendations provided.
