Description of problem:
This was already fixed in the 32-bit version of RHEL 2.1.
sd_init_onedisk() waits approximately 100 seconds for each CLARiiON 
passive-mode device to spin up when the device driver is loading.  
Since these passive-mode devices are non-responsive to the
START_STOP SCSI message used to spin up non-removable media, the 
delay is unnecessary.

I would like to request that the RHEL 2.1 AS 64-bit sd.c be changedto 
match the changes made to RHEL 2.1 32-bit?  This was fixed for 32-bit 
RHEL 2.1 - see bugzilla #68883.
QLogic driver v6.04.01 is being used.


Version-Release number of selected component (if applicable):
kernel-source-2.4.18-e.37

How reproducible:
Always

Steps to Reproduce:
Attach to the CLARiiON array that has passive-mode devices and boot 
up your RHEL 2.1 64-bit Linux host.  The host will attempt to spin up 
each individual passive mode device.  For instance, with the 100 
second delay for each passive I/O path, a RHEL 2.1 64-bit 
configuration with 128 SCSI disk devices, 64 of which are passive, 
will incur a 1 hour 46 minute delay on bootup.
