Installing and Configuring the HBA and Driver

Here is an example of a disconnected LUN 0 being reported:

(CLARiiON Only) Passive-Not-Ready/ FailOverMode SP Bit Setting and Spinning Up

Devices

Two bit settings are required for PowerPath use on CLARiiON

arrays. The Array CommPath and FailoverMode bits are enabled by

default.

The FailoverMode bit setting provides for Passive-Not-Ready LUN

visibility.

The ArrayCommPath bit setting provides a pseudo-logical LUN 0

(LUNZ) for when a LUN 0 is not configured for a host.

If the FailOverMode is enabled on an SP for a Linux host, devices will

be reported as Not Ready. Depending on the OS, the host may still try

to spin up the devices.

The standard Linux behavior is to attempt to spin up the Not Ready

devices. This is acceptable Linux SCSI behavior, but a 100-second

delay is initiated for each Not Ready device encountered on particu-

lar distributions.
