How to rebuild the /etc/path_to_inst without un-encapsulating the root disk

Note : This will only work if the rootdisk isencapsulated. You don't have to break the root mirror.

Under VERITASVolume Manager (tm) rootdisk encapsulation, the administrator must take an extrastep to ensure the path_to_inst file is created and populated. Thedifference lies in the root device. This value is not the same as the defaultoffered during the boot, use the value specified for rootdev in the /etc/system file.

At the OK prompt, do thefollowing:

1. boot-ar

Rebooting with command: boot-ar                                      
Bootdevice: /pci@1f,0/pci@1,1/ide@3/disk@0,0  File and args:-ar

2. At the following prompts, just hitenter:

Enter filename[kernel/sparcv9/unix]:  << --------Hitenter
Enter default directory for modules [/platform/SUNW,Ultra-5_10/kernel/platform/sun4u/kernel /kernel /usr/kernel]:
Name of system file[etc/system]:   <<< Hitenter

SunOS Release 5.8 VersionGeneric_108528-15 64-bit

3. When the system asks about rebuilding thepath_to_inst, type yes

The/etc/path_to_inst on your system does not exist or isempty.
Do you want to rebuild thisfile [n]? yes  <<<<--------------type yes

root filesystem type[ufs]:  <<<<------------ Hit enter

4.When you get to the following prompt enter/ pseudo/vxio@0:0

Enterphysical name of root device [/pci@1f,0/pci@1,1/ide@3/disk@0,0:a]:/pseudo/vxio@0:0  <<<<---- Enter this(this comes from /etc/system).

System will now bootOK.
