copy failing disk to Spare

Hi Guys,

I have a failing 4gb (c0t5d0) drive that contains lvol4 -8 on hp-ux. It's not the boot disk but is part of VG00 volume group. Within that group, I have a disk (c0t4d0) of the same size that has 1 lvol on it for swap(4gb) I also have a seperate 1.5 gb swap volume on another physical disk

Can I remove the 4gb swap volume(lvol9) and then somehow copy the failing disk to the now empty swap disk. If this is possible, can you please help me with the order/commands I will need to perform this.

I'm assuming the following will work just need clarification -

goto Sam and remove the 4gb Swap volume from physical disk c0t4d0

copy from c0t5d0 to c0t4d0 using 'dd if=c0t5d0 of=c0t4d0

shut server down and phyisically swap c0t5d0 for a new drive,

change c0t4d0 to c0t5d0 physical address

then reboot

does this make sense?

I'm assuming the new empty physical disk will need to be c0t4d0. Will the system recognise that lvol4-8 are on the right disk?

Any help with this will be great as I don't want to lose any data

installboot(1M)                                                                                                                    installboot(1M)

NAME
installboot - install bootblocks in a disk partition SYNOPSIS
installboot bootblk raw-disk-device The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition. The ufs boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be found using the -i option of uname(1). The installboot utility is a SPARC only program. It is not supported on the architecture. users should use installgrub(1M) instead. bootblk The name of the bootblock code. raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is read- able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive. Example 1: Installing UFS Boot Block To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use: example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0 /usr/platform/platform-name/lib/fs/ufs directory where ufs boot objects reside. /platform/platform-name/ufsboot second level program to boot from a disk or CD See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ od(1), uname(1), boot(1M), init(1M), kadb(1M), kernel(1M), monitor(1M), reboot(1M), rpc.bootparamd(1M), init.d(4), attributes(5) WARNINGS
The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device. 11 Apr 2005 installboot(1M)
