/stand Bad Block Realocation

Hp Doc says :
---------------------------------------------------------
Managing Disks Using the Logical Volume Manager (LVM) - Bad Block
Relocation

If as a result of a defect on the disk, LVM is unable to store data, a
mechanism is provided to store it at the end of the disk. If your disk
supports automatic bad block relocation (usually known as "hardware
sparing"), then LVM's bad block relocation mechanism is unnecessary.
Bad block relocation is in effect by default when a logical volume is
created. You can use the -r n option of lvcreate(1M) to disable the
bad
block relocation feature.

NOTE Bad block relocation is not supported for root, swap, or dump
logical volumes.

My Question is :

What about /stand? Does it support Bad block relocation ?

Hi:

Bad block relocation cannot be specified for the /stand filesytem.

The boot logical volume must be the first one on the physical volume. and must be contiguous, without bad block relocation.

Hi Sundara,

If you look at the document "Administrating a system: Managing Disks and Files" (B2355-90742) Page 344,

http://docs.hp.com/hpux/pdf/B2355-90742.pdf

there is a NOTE: next to the section you quoted, which says

/Begin Quote/
NOTE Bad blcok relocation is not supported for root, swap or dump logical volumes.
/End Quote/

In addition to what James said, /stand has to be on a HFS filesystem besides being on the first one on the physical volume, and contiguous and without bad block relocation.

Yes I do know.../stand has to be a HFS File

System also lvol1 in the Root VG also

But I was wondering why nothing has ever been

even mentioned in the HP DOcs..
