How the disk crossing (%) is calculated from navi cli output?
Hi all,
Would you please let me know how the disk crossing (%) is calculated from navi cli output? And how is it translated to LUN level?
Is it calculated this way:
Stripe Boundary Crossing / (Read Requests + Write Requests) * 100%
Thanks

It's a calculated value - from HELP in Unisphere
Percentage of host requests that require I/O to at least two disks compared to the total number of host requests.
A single disk crossing can involve more than two disk drives.
