Configuring a Symmetrix boot device
47
Configuring a Boot Device on the EMC Storage Array
Note: The information about the boot device's path. This information
will be useful later, in the procedure for modifying OpenBoot. In the
previous example, your boot device's path is
/pci@1f,4000/QLGC,qla@4/sd@0,0.
Copying required files
Use ufsdump and ufsrestore to copy the required files and
directories from the host source drive to the Symmetrix boot device.
1. At the %> prompt, type mount /dev/dsk/c3t0d0s0 /mnt and
press ENTER to mounts the root directory of the Symmetrix
device to /mnt.
2. Use the ufsdump command to create the required directory
structure on the new Symmetrix device and copy the files.
Below is an example where the current operating system is
located on
/dev/dsk/c0t0d0.
Example: At the %> prompt, type the following and press ENTER:
ufsdump 0f - /dev/dsk/c0t0d0s0 |( cd /mnt; ufsrestore rf - )
When the above command completes, the Symmetrix device
(c3t0d0s0) will have the complete image of the root partition.
3. In the
/mnt/etc directory update the vfstab file to indicate the
Symmetrix boot device address to be mounted during boot.
Modify all partitions that will be located on the Symmetrix boot
device.
a. At the %> prompt, type cd /mnt/etc and press ENTER.
b. At the %> prompt, type vi vfstab and press ENTER.
