我有一个OEL服务器通过光纤连接到NetApp SAN.如何在操作系统看到队列深度时查看队列深度?
lspci的输出:

我的NETAPP:
ls /proc/scsi/qla2xxx
1
ls /proc/scsi/qla2xxx/1 | grep -i -A1 -B1 "queue depth"
Total number of interrupts = 30686605
Device queue depth = 0x20
Number of free request entries = 1842
所以x20是十进制的32,
这是你正在寻找的#.

编辑:其他一些方法可以看到:cat / sys / module / qla2xxx / parameters / ql2xmaxqdepth
