| Post subject: | LD to vvol mapping? |
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? |

So somehow I missed the obvious the first run through the commands, the relevant command is showldmap (duh), and it led us to the offender and we've asked them if they can tone down their work and the answer was no, so the only solution is to turn AO back on for tonight to move their stuff up from NL (It's been off for the last month or so as we've been rebalancing into our recent expansion purchase). |
