physical disk layout for FC60 disk array

Hi, We have a FC60 disk array in which we are using hardware mirroring(1+0).The FC60 array is configured with split bus configuration.
I need to prepare the diagram of physical layout of disk in the disk array to find out which disk belong to which LUN and volume group.
I have the ioscan output.(ioscan -fn C disk).

IS it possible to create the physical sisk layout using ioscan output,vgdisplay,pvdisplay,lvdisplay commands.

Thanks
AR

ps:I do not have access to SAM.

Hi,

You might want to try a program like (XVG) in this threads.

Hi,

You might as well have a look at the great sysinfo tool.

Re: physical disk layout for FC60 disk array

Hi,

much easy if you start in sam , disk and file system -> disk device
Now you can see FC60 LUN associate with hardware path.
if you view more info by select controller can know each individual disk belong to which LUN.

OK , from hardware path use ioscan to get device file.
At this steps know LUN <-> device file.
use
#strings /etc/lvmtab
know disks(LUN) in volumn group.
then use bdf you know file sytem.
enjoy any little thing in my life

Re: physical disk layout for FC60 disk array

The LVM commands won't give you all the information you want. You can use the 'amdsp' command to get a picture of what the array looks like physically - ie what LUNs map to what physical disks inside the enclosures. Try:

# amdsp -a

You can then use ioscan / pvdisplay / vgdisplay / lvdisplay to get the LUN -> vg -> lvol mapping.

Re: physical disk layout for FC60 disk array

In this case, STM (Support Tools Manager) would be great rather than others.

# mstm
Highlight one FC60 hardware path with description of A5277A using spacebar and run information on the menu.
Tools -> Information Tool -> Run

If you don't have STM installed, get it on the web "www.software.hp.com".
It's free.

Hope this helps,

Never say "no" first.
