encapsulated root disk replacement

Hello,

I have a Sparc system with encapsulated disks.
Because of disk errors I had to replace rootdisk,
I did it with
vxdiskadm 4)
replacement, vxdctl disable/enable,
vxdiskadm 5)

After it it the system boot failed, dropped back to the ok> prompt, message was:
The file just loaded does not appear to be executable.
I could boot up only from the rootmirr only.

vxdisk list shows

Code:

DEVICE       TYPE      DISK         GROUP        STATUS       c#t#d#_NAME   
c0t0d0s2     sliced    rootdisk_1   rootdg       online       c0t0d0s2
c1t0d0s2     sliced    rootmirr_1   rootdg       online       c1t0d0s2
c1t2d0s2     sliced    COLDMIRR_1   rootdg       online       c1t2d0s2

The question is that vxdiskadm 4/5 handles the installation of the boot record too on the replacement root disk or there is necessary an additional step to install it ? I found UFS related installboot recommendations and vxrelated one too.

As I checked towards I found another disk in the volume instead of the replacement c0t0d0:

Code:

# vxprint -ht -g rootdg
v  global_n1    -            ENABLED  ACTIVE   1048707  ROUND     -        fsgen
pl global_n1-01 global_n1    ENABLED  ACTIVE   1048707  CONCAT    -        RW
sd COLDMIRR_1-04 global_n1-01 COLDMIRR_1 59585625 1048707 0       c1t2d0   ENA
pl global_n1-02 global_n1    ENABLED  ACTIVE   1048707  CONCAT    -        RW
sd rootmirr_1-05 global_n1-02 rootmirr_1 70072695 1048707 0       c1t0d0   ENA

And as I found the partitioning of c0t0d0 is compleetly different from the rootmirr_1 c1t0d0s2.
I don't understand what went wrong ... Have to create the slices by hand first, only then I can use the vxdiskadm replace function ?

Thanks in advance,
Regards,
GG

vximportdg

vximportdg(1M)															    vximportdg(1M)

NAME

       vximportdg - import a disk group into the Veritas Volume Manager configuration

SYNOPSIS

       vximportdg daname new_dgname

DESCRIPTION

       The  vximportdg	utility  performs  a temporary import of the disk group contained on the disk device specified by daname to the disk group
       specified by new_dgname.  As the persistent disk group information is not changed within the private partition of the  affected	disk,  the
       import is only valid for the duration of the bootload or until a vxdg deport is performed.

ARGUMENTS

       daname	 Specifies  the  device name (disk access name) of one of the member disks of the disk group to be imported. The other members are
		 imported automatically.

       new_dgname
		 Specifies the disk group to be imported.

USAGE

       One reason to use the vximportdg utility is to import a second generation of the rootdg disk group so that its objects  are  available  for
       use  while a system is running on a different rootdg.  To prevent volumes on the second generation rootdg from having the same device minor
       numbers as volumes (such as rootvol) on the active rootdg, the importation assigns temporary non-conflicting device minor numbers.  If this
       occurs, vximportdg outputs warning messages detailing the mapping of the minor numbers.
