Before and after formatting a VMFS volume on a Fibre-Channel or iSCSI volume, the storage can be addressed in many different ways: • By its Linux device name: /dev/sdk • By its VMkernel "runtime" device name: vmhba1:0:0:15 • By is unique Network Address Authority (NAA) value: naa.6000... • By its volume name, which has to be unique to the ESX host: myvmfs • By its data store name, which has to be unique to vCenter: myvmfs • By its Universally Unique Identifier (UUID): 47877284-77d8f66b-fc04-001560ace43f It's important to know that as with the NAA, the UUID value must be completely unique and an ESX host cannot have two UUIDs that are exactly the same presented to it at the same time. UUIDs are generated by using three core variables, including date, time and LUN number in order to guarantee that the UUID value be absolutely unique. This can cause some interesting, or shall I say unpleasant consequences if you are not consistent in your LUN numbering. That is to say problems can occur if ESX1 believes the LUN/Volume number is 15, and another ESX hosts believes the same block of storage is LUN/Volume 20. It's also worth saying that currently virtual machines do not find their VMDK and VSWP files using the friendly volume/data store name. If you examine the contents of a .VMX file you will see references to the UUID value. | Добавлено: Michigun Цитата: "и все таки" звучит будто ранее кто-то это опровергал | мне интересно в первую очередь, какой софт заточен на решение тех проблем, с которыми столкнулся я а не то, какие горизонтальные рынки интересны вмваре Добавлено: А вот здесь http://searchvmware.techtarget.com/news/2240031051/Will-VMware-SRM-lose-the-R-and-become-Site-Manager - Майк Лаврик писал о том, что SRM будет как раз обслуживать M&A (то есть тот же кейс, для которого AD сайты и трасты) Только, как я погляжу, прогноз не сбылся? | Всего записей: 17108 | Зарегистр. 14-10-2001 | Отправлено: 18:18 17-03-2012 | Исправлено: LevT, 18:42 17-03-2012 |
