Preventing a scan of the RAID during bootup
I have a RH 7.3 server that needs a restart today after putting a patch in place. The last time I rebooted this box was almost a year ago and when the uptime is quite long, Linux likes to check all the disks for errors, including the RAID. This adds almost 1.5Hrs to my bootup process
.
Does anyone know a command/feature to turn off the scan before I shut down?

UPTIME(1) Linux User's Manual UPTIME(1)
NAME
uptime - Tell how long the system has been running.
SYNOPSIS
uptime
uptime [-V]
DESCRIPTION
uptime gives a one line display of the following information. The current time, how long the system has been running, how many users are
currently logged on, and the system load averages for the past 1, 5, and 15 minutes.
This is the same information contained in the header line displayed by w(1).
System load averages is the average number of processes that are either in a runnable or uninterruptable state. A process in a runnable
state is either using the CPU or waiting to use the CPU. A process in uninterruptable state is waiting for some I/O access, eg waiting for
disk. The averages are taken over the three time intervals. Load averages are not normalized for the number of CPUs in a system, so a
load average of 1 means a single CPU system is loaded all the time while on a 4 CPU system it means it was idle 75% of the time.
FILES
/var/run/utmp
information about who is currently logged on
/proc process information
