Scan new Disk device

[Jack Fan]

All,

I have a RHEL 3 AS server with HBA card, now I assign a SAN vdisk device to this server and want to create a new mount point on server.

Is't possible to scan new SAN vdisk device and fdisk it without reboot server on RHEL 3 AS? How?

Thanks,
Jack Fan

Hello,

have a cat /proc/scsi/qla2300/0 to see if host see devices.
(you have to replace qla2300 by you actual driver.)

maybe you have something like /opt/hp/hp_fibreutils/hp_rescan ?

The command hp_rescan can do that, it's included in the fibreutils package.

You can also try with the rescan-scsi-bus.sh shell script, but normally, hp_rescan is better.

Hi Jack,

What's your HBA type?

With Qlogic card yes you can but not guranteed with out reboot. The method is almost like reboot means you have to unload the module.

First you should do hp_rescan. After this step your Linux will find new unpartition disks (LUNs).
Then you should make required partitions on disks with "fdisk" command.
And finally you should execute partprobe command.
partprobe is a program that informs the operating system kernel of partition table changes, by requesting that the operating system re-read the partition table.
