I am having problems with a CMD CRD-5440 with multiple luns. The config is 2
drive trays, each on their own channel on the CMD, and one host channel to
the FreeBSD 3.4 box. I was not experiencing these problems untill the 2nd
drive tray was added, making the CMD use 2 luns. So far I have tried to
set the number of max tags by editing sys/cam/cam_xpt.c and adding the
following entry.
/* Reports QUEUE FULL for temporary resource shortages */
{ T_DIRECT, SIP_MEDIA_FIXED, "CMD TECH", "CRD-5440*", "*" },
/*quirks*/0, /*mintags*/24, /*maxtags*/32
That does not seem to have helped.. The following are scsi errors I am
seeing.
/kernel: (da2:ahc1:0:1:0): SCB 0x18 - timed out while idle, LASTPHASE ==
0x1, SEQADDR == 0xa
