Disk Utilization

[zsujith]

Hello All,

In one of our server the glance shows 100% Disk utilization.

I need to find out which disk is utilizing the most and also need to generate 24 hour report to present it to customer.

Please help in generating report i.e. text and graphics using sar, glance or gpm.

Thanks & Regards

[Jeeshan]

you can see the disk wise utilization using glance

#glance -u

or can use sar utility

#sar -d 5 5

Hello,

I need to generate report of which SAN disk or it associated logical volume is causing the disk utilization.

Regards

[Jeeshan]

which SAN you are using?

[zsujith]

Hello,

It is HITACHI OPEN-V SAN disk.

Regards

[Jeeshan]

so, you may prepare the disk utilization report from Storage system. not from system. check in the control utility of Hitachi if any and check the LUN's utilization. and which disk(s) are belongs to that LUN.
