How to check if DISK is stripped or not

[Sushil Singh_1]

Hi All,
Just wondering how can I check if the disk on HP-UX 11i is stripped or not.

Thanks
Sushil Singh

Hi Sushil,

Can't really tell at the device level, but a lvdisplay -v will show whether the LV is striped as well as what PV(s) contain it.

Rgds,
Jeff

Do an lvdisplay on one of the lvols in the vg.

Then you'll see the following two fields:

Stripes 0
Stripe Size (Kbytes) 0

If you add a -v arg, it should show you how the extents are distributed across the striped disks.

HTH.

Sushil,

You have to check the individual logical volumes..

# lvdisplay -v /dev/vg??/lvol??

Check the columns - Strips, Stripesize & Allocation.

Thanks,

Sundar.

If you meant by "disk" is the volume (or LVOL) underneath your filesystems -- then yes displaying the properties of the LVOL if using LVM will show you how they are built. You have not exactly told us if you are using VxVM or LVM.. If VxVM, then you could do a "vxprint -Aht" and it will be obvious -- striped volumes will have a STRIPE column output.
.
If you want to know how the "disks" -- assuming these are from an external SAN/Array - then there is NO way to tell whether these are 'striped' LUNS on the array itself... You will need to ask your array/SAN administrator... Remember, there are two RAID congigurations - one on your array/SAN hardware and on your host level.
