Carl,

There's a public report for a similar issue in now:

http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=80268

The equation to combine these is:
if (Low >= 0) x = High * 2^32 + Low
if (Low < 0) x = (High + 1) * 2^32 + Low

In this instance:

High = 2

Low = -1834563852

since Low < 0, use the second equation:

x = (2+1) * 2^32 + (-1834563852) = 12884901888 - 1834563852 = 11050338036

Good luck,

-Joshua

Subject: SNMP Question

What would be the correct way to calculate the total size of an aggregate with the following SNMP information:

dfHighTotalKBytes = 2

dfLowTotalKBytes = -1834563852

I thought it would be 2*4294967295 + 1834563852 = 10,424,498,442

But this comes out 625,839,594 short of the df –rk output:

Aggregate total = 11,050,338,036

The MIB is at version 1.17.3.

Thanks,

--Carl
