Post-installation configuration for Red Hat Enterprise Linux
3.0 and 4.0
After installing Smart Array Multipath software on a server with a Red Hat Enterprise Linux operating
system, configure for multipath operations.
Review the following sample configuration procedure. This procedure assumes that the user wants to set
/dev/cciss/c1d0p2 and /dev/cciss/c2d0p2 to point to the same volume as a multipath device.
To configure the system for multipath use, complete the following steps:
1.
Ensure that the MSA500 G2 storage system contains two identical MSA500 G2 controllers
connected to the same logical volume.
2.
To create multipath device /dev/md0, enter the following command:
mdadm -–create -–level multipath –n 2 /dev/md0 /dev/cciss/c1d0p2
/dev/cciss/c2d0p2
3.
To review the status, enter the following command:
mdadm –D /dev/md0
The output displayed must be similar to the following:
/dev/md0
