Configuring a PowerPath Boot Device on Solaris

Installing a Bootblk Install a bootblk (the information required by the host to boot the operating system) on the root partition of the storage system boot device.

1.Use the uname -acommand to determine the architecture of the workstation. This determines the directory in /usr/platform where the bootblk will be found. The following example shows sun4u as the architecture, and subdirectory for /usr/platform.

Example: At the %> prompt, enter uname -aand press ENTER to display a line similar to the following:

SunOS patriot 5.8 Generic_108528-15 sun4u Sparc SUNW,Ultra-60

2.At the %> prompt, enter a command like the following to install a bootblk onto the storage system boot device:

/usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk\

/dev/rdsk/ccontroller_numbertstorage_system_device_target_numberd0s0

For example, enter the following command to install a bootblk onto a boot device of Target 0 LUN 0 on controller 3:

/usr/sbin/installboot /usr/platform/sun4u/lib/fs/ufs/bootblk /dev/rdsk/c3t0d0s0

Copying Required Use ufsdump and ufsrestore to copy the required files and

Filesdirectories from the host source drive to the storage system boot device.

1.At the %> prompt, enter mount /dev/dsk/c3t0d0s0 /mnt and press ENTER to mount the root directory of the storage system device to /mnt.

2.Use the ufsdump command to create the required directory structure on the new storage system device and copy the files.

In the following example, the current operating system is located on /dev/dsk/c0t0d0.

Example: At the %> prompt, enter the following command and press ENTER:

ufsdump 0f - /dev/dsk/c0t0d0s0 ( cd /mnt; ufsrestore rf - )

When the above command completes, the storage system device (c3t0d0s0) will have the complete image of the root partition.
