AutoPath (XP12K Storage) and LVM - Any LVM Object Settings I need to Set?

[Alzhy]

Migrating from EVA to XP storage... (via pvmoves and vxdump/vxrestore). I use the main path on my XP LUNs in my LVM configuration: ie:

# autopath display all

HPswsp Version : A.3.0E.00F.00F

Details for path : /dev/dsk/c102t15d7

Load Balance Policy : No Load Balance

=========================================================
Device Paths Device Status
=========================================================
/dev/dsk/c102t15d7 Active
/dev/dsk/c101t15d7 Active
=========================================================


Are there any PV settings I need to change.. ie. timeout values, badblock relocation, etc...

hi,

for OPEN-V alias XP lun's is great idea to change the bad block reallocation to NONE.

why ? the XP exports just the luns and XP by itself recognize if there are any badblocks. it's just waste of space if you let it enabled. means : in a case XP detects any problem and LVM noticed it -> LVM realocates the badblock and you lost 1 block :D but XP will reallocate it internally by itself. so you lost 2 blocks and not just one bad :D

we also use this badblock reallocation switched of also for EVA. I'm surprised that someone has enabled this on :( interesting. maybe there was a reason.
