如何检查当前的队列深度值?

我有一个通过光纤连接到NetApp SAN的OEL服务器。 如何在操作系统看到它时查看队列深度?

lspci输出:

 05:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02) 05:00.1 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02) 08:00.0 Fibre Channel: QLogic Corp. ISP2532-based 8Gb Fibre Channel to PCI Express HBA (rev 02) 08:00.1 Fibre Channel: QLogic Corp.

来自lsmod输出:

 qla2xxx 1262209 352 scsi_transport_fc 83145 1 qla2xxx scsi_mod 199641 15 be2iscsi,ib_iser,iscsi_tcp,bnx2i,libcxgbi,libiscsi2,scsi_transport_iscsi2,scsi_dh,sr_mod,sg,qla2xxx,scsi_transport_fc,libata,cciss,sd_mod

在我的NETAPP上:

 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。 你可以在这里阅读关于NETAPP的计算:

编辑:一些其他的方法看到: cat /sys/module/qla2xxx/parameters/ql2xmaxqdepth

最简单的方法是

 cat /sys/block/<sdX>/device/queue_depth
