Re: expand database volume

lol
Yeah, that's what I meant. (You're right; man that takes me back a few
years. I remember running that command, too.)

Don't you mean Diskpart? Diskperf was a command for enabling the physical
disk perforance counters circa Windows NT and 2000.

Some vendor's can do this for you, others leave you to your own devices.
Your best bet would be to check with your storage vendor to inquire as to
the preferred method..

I'm not sure about W2K8 but I've used diskperf (from MS) to expand the
volume size once I've added more disc space to the lun.
You can have different size drives but in some cases, the size of the
larger drive is reduced to the size of the smallest drive. However, you
could create a new R5 with the larger drives and attach that to the lun.
Of course, since it's a new R5 you'd lose some drive space from the 3x500
due to striping. Lot of it depends on the san vendor you're using. I'm
only familiar with EMC (fc4700 and cx500)

Hi,

We need to have more space on our mailbox database volume, so we are
adding
more disks to our SAN. Store database is on a RAID5 LUN. If we expand
our LUN
with more hard disks, can the OS windows 2008 expand the volume in which
databses are stored. Also can I have a single RAID 5 configuration with
different capacity hard drives, example can I expand (add) the existing
4X300GB with 3X 500GB.

thanks

Can't your SAN expand the LUN on the fly? I work for a SAN vendor who
has host based software that will do that for you?
And anyway, Windows 2008 will also do that so long as there is space
available for the LUN to do it.
