博客围绕Red Hat Enterprise Linux 5和6系统展开，探讨了dev_loss_tmo的默认值和最大值问题。默认值因驱动/设备而异，如Qlogic适配器为35秒，Emulex适配器为30秒，可通过模块参数修改；最大值为600秒，设为0或大于600则用驱动内部超时值。

What’s the maximum value of dev_loss_tmo?

决议

The default dev_loss_tmo value varies, depending on which driver/device is used. If a Qlogic adapter is used, the default is 35 seconds, while if an Emulex adapter is used, it is 30 seconds. The dev_loss_tmo value can be changed via the scsi_transport_fc module parameter dev_loss_tmo, although the driver can override this timeout value.

The maximum dev_loss_tmo value is 600 seconds. If dev_loss_tmo is set to zero or any value greater than 600, the driver's internal timeouts will be used instead.
