physical disk layout for FC60 disk array

Aashish Raj — Fri, 12 Apr 2002 05:33:46 GMT

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.

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.

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.

Steve

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,
