So I'm trying to analyze a performance anomaly and I'm using histld to find the LD's with slow service times, but now that I have the LD's I need to map those back to vvols (and yes I realize some will be villains and some will be victims, but it still gives me somewhere to look). The problem is the results look like this:
Code:
10:30:40 08/12/2014 ----------------Time (millisec)----------------- ---------------Size (bytes)----------------
Ldame 0.50 1 2 4 8 16 32 64 128 256 4k 8k 16k 32k 64k 128k 256k 512k 1m
tp-15-sd-0.1 1514 310 294 250 323 873 1830 1582 670 120 2063 2040 2295 645 723 0 0 0 0
tp-8-sd-0.12 1206 209 222 609 1002 745 762 903 593 86 697 540 3417 1054 543 73 13 0 0
tp-10-sd-0.4 6211 785 493 105 6 95 685 1403 836 156 7735 169 60 32 1172 29 55 1523 0
tp-4-sd-0.45 1319 0 1 1 11 20 73 264 399 196 1404 84 517 154 100 22 3 0 0
Obviously those tp-* names are from thin provisioning, but they don't mean anything to a human. Perusing the CLI reference guide doesn't give any obvious way to map LD's to VVOL's, does anyone have a handy method?
