_netdev The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system).
This device is not a network device (this a SAN not a NAS). To the OS it looks like a normal SCSI attached device, it's /dev/sdb. In the blade there is a HBA (Qlogic) card, and it's connected through FiberChannel. If I understand these terms correctly, it has nothing to do with the network.

Hi
I have an IBM blade with internal harddisks, in hardware RAID1. I've installed a CentOS 6 64bit on it, everything works just fine.
After the installation, I've presented a vdisk to the blade from an external SAN (an HP EVA4000), connected through FiberChannel. I've partitioned the disk, formatted it and mounted it under /store, then added it to fstab. Everything was fine, until I rebooted.
At boot I'm getting the following error for /store:
Mounting local filesystems: mount: special device UUID=2a587e95-4a6c-4336-bb8b-f0d066905bc5 does not exist
It just goes on to boot without mounting this filesystem. After it boots, I can log in and give the command "mount -a", and it gets mounted without problems.
As far as I can tell, the reason for this is that CentOS doesn't wait for the external disk to get initialized fully and it just doesn't find it at boot time. I have other CentOS blades, installed and booting from the same SAN and they work without problems, but I noticed that they wait a little bit longer at boot.
Am I missing some stuff from initrd? What can I do to make it wait for the block device a bit longer before it tries mounting it ?
Thanks!
