Hi Debendro,

By default all block devices are accepted in LVM. If you want LVM to watch
out  only for certain type of devices, you have to put an appropriate
filter.

e.g to exclude CDROM you may put

filter = [ "r|/dev/cdrom|" ]

Given your requirement, you may try

filter = [ "a/sda[1-9]$/" "a/emcpower.*/" "r/.*/" ]

And don't forget to run vgscan -vv after making changes to lvm.conf, also be
careful if running on production, keeping the backup of lvm.conf is must.

Cheers!
Yash
