Hi Folks, I had requested a similar feature back in Jun-2009 and one of the LDOM active member (Octave Orgeron) submitted and RFE.
Here is the link of it, http://defect.opensolaris.org/bz/show_bug.cgi?id=9466 Has this RFE being implemented in the latest release of LDOM, If not any plans to add it and when? Thanks for your everybody's time :) Regards, AN. > From: ldoms-discuss-request at opensolaris.org > Subject: ldoms-discuss Digest, Vol 30, Issue 18 > To: ldoms-discuss at opensolaris.org > Date: Thu, 21 Jan 2010 12:00:00 -0800 > > Send ldoms-discuss mailing list submissions to > ldoms-discuss at opensolaris.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss > or, via email, send a message with subject or body 'help' to > ldoms-discuss-request at opensolaris.org > > You can reach the person managing the list at > ldoms-discuss-owner at opensolaris.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of ldoms-discuss digest..." > > > Today's Topics: > > 1.
