How to delay resume after suspend to get disks ready, using kernel command line switch?

[Ram Ramesh]

Problem:

I am having a problem with ubuntu 14.04 resume from suspend. I suspect a 
race condition in boot process. I have a mpt2sas (LSISAS2008: 
FWVersion(20.00.07.00)) host adapter to which several of my disks are 
attached. On occasions, there is a delay before these devices become 
available. However, kernel tries to assemble RAID6 that includes these 
disks before they become available. As a result the array gets assembled 
in a degraded mode.

My question:

I like to tell kernel to delay resume until LSI card finishes its card 
identifying devices. Can I use resumedelay/rootdelay switches in 
grub.cfg to accomplish this? If so, which one I should use?
