Boot archive file sizes are different on cluster units

Hi experts,

I would have a question on boot archive files on solaris10 platform running on T5220 cluster servers.

When we check the /platform/sun4v directory , and perform boot archive-list , we see that on both units same files exist. And when we mount the boot archive we see that all files have same file sizes..

Code:
Inactive
  Filesystem             size   used  avail capacity  Mounted on
  /dev/md/dsk/d2         4.4G   2.9G   1.5G    66%    /
   
  Active
  Filesystem             size   used  avail capacity  Mounted on
  /dev/md/dsk/d2         4.4G   3.0G   1.4G    68%    /

Would you please comment on why these boot archive file sizes are different on both units ?

Appreciate your quick response as always..

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)
