Exit Maintanance Mode v riadku v Servisnej Konzole

Moze sa stat, ze date ESX server do Maintanance Mode a nebudete ho vediet dat spat do normalneho modu. Treba ist do servisnej konzoly ESX servra. Bud cez konzolu alebo SSH klientom typu Putty.

Tu je prikaz servisnej konzoly ako zistit, ci je server v Maintanance Mode:
vimsh -n -e /hostsvc/runtimeinfo | grep inMaintenanceMode

Odist z Maintanance Mode:
vimsh -n -e /hostsvc/maintenance_mode_exit

Nastavenie ESX servra do Maintanance Mode:
vimsh -n -e /hostsvc/maintenance_mode_enter

pri citani RSS kanalov o virtualizacii som nadabil na zaujimavy text:

" It's worth to remember in fact that Fedora is controlled by Red Hat, which is in hasty competition with Novell. But while Xen is implemented by both companies, only Novell has a tight partnership with Microsoft, which has a tight partnership with Citrix, which is now able to influece the Xen development."

Je mozne, ze si tento text precitate i viackrat za sebou a stale bude malo :))))
Neviem ci si tento text nedame ako headline tohoto blogu Virtualizuj!? :)
Co ty na to Julo?

Sun vs VMware?

Dnes preletela sprava, ze Sun akvizuje Nemecku spolocnost innotek, co je provider open source virtualization software nazvaneho VirtualBox. Tento krok posilnuje viziu Sun xVM platform voci VMware. Po VMware akviziciach Propero (UK) a Dunes Technologies (Switzerland), je Sunom akvizovany innotek tretou vaznejsou akviziciou v kratkom case v regione EMEA.

Moznost instalacie ESX 3i na lokalny disk

Existuje moznost lokalnej instalacie novej verzie ESX 3i, ktora nema servisnu konzolu. Treba mat instalacne CD a podporovany hardware. Zatial je to iba DELL PE2950. V experimentalnom stadiu je podpora pre HP DL385.


Doporucujem v pripade blizsieho zaujmu pozriet do 3i Setup Guide: http://www.vmware.com/pdf/vi3_35/esx_3i_i/r35/vi3_35_25_3i_i_setup.pdf
