disk RAID

[JR Haley]

We have 7 disks in a RAID arrangement on a D370 running HP-UX 11.11. How do we display or find out if the disks are mirroring each other in the array? We are seeing data recovery when disks are replaced but only on raw lvols - not on file systems. A puzzler...

What kind of raid array device are you using?

For mirroring, do a "lvdisplay -v | more" on your logical volumes, and if the mirror copies is greater than 0 then you have mirror copies.

Hi,

Which type of RAID box are you using? Normally in an external RAID box, you need to connect the console terminal to the console port of it, inorder to see the actions/status of the disks. The manual will give you a good idea about performing these tasks.

To determine if your are using software RAID, mirrordsk/ux, do lvdisplay and check for mirrored copies of each lvol. if not, then you are using HW raid, check your array manual in that case.

try

#vgdisplay -v
and
#lvlnoot -v
