Thanks to everyone for their input it was helpful. I have another question. For RAID 1 does it matter which slot I put the spare drive into? Ex. I pull a drive from slot 1 and keep as emergency backup. Insert a spare and have it rebuild (does it need to be blank or can it have old data?). Perform upgrade and system has problems so I want to go back. If I pull both drives out and insert the emergency backup into slot 0 and powerup the server this is no problem correct? Or do I need to put the emergency into slot 1 power up and then insert another into slot 0 to rebuild the mirror. I think there are a couple questions in there somewhere.<O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy"><O:P> </O:P></SPAN></FONT></P> <DIV><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy">Eddie Klaczko</SPAN></FONT><FONT color="navy"><SPAN style="color:navy"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy">IP Telephony / Network Specialist</SPAN></FONT><FONT color="navy"><SPAN style="color:navy"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy">CC <ST1:PLACE w:st="on"><ST1:PLACENAME w:st="on">Schaumburg</ST1:PLACENAME> <ST1:PLACETYPE w:st="on">School District</ST1:PLACETYPE></ST1:PLACE> 54</SPAN></FONT><FONT color="navy"><SPAN style="color:navy"><O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy"><A href="mailto:eklaczko@sd54.org">eklaczko@sd54.org</A></SPAN></FONT><O:P></O:P></P> </DIV> <DIV> <DIV class="MsoNormal" align="center" style="text-align:center"><FONT size="3" face="Times New Roman"><SPAN style="font-size:12.0pt"> <HR size="2" width="100%" align="center" tabindex="-1"> </SPAN></FONT></DIV><P class="MsoNormal"><B><FONT size="2" face="Tahoma"><SPAN style="font-size:10.0pt; font-family:Tahoma;font-weight:bold">From:</SPAN></FONT></B><FONT size="2" face="Tahoma"><SPAN style="font-size:10.0pt;font-family:Tahoma"> cisco-voip-bounces@puck.nether.net [<A href="mailto:cisco-voip-bounces@puck.nether.net">mailto:cisco-voip-bounces@puck.nether.net</A>] <B><SPAN style="font-weight:bold">On Behalf Of </SPAN></B>Keith Klevenski<BR> <B><SPAN style="font-weight:bold">Sent:</SPAN></B> Friday, November 03, 2006 10:13 AM<BR> <B><SPAN style="font-weight:bold">To:</SPAN></B> Jason Aarons (US); <A href="mailto:cisco-voip@puck.nether.net">cisco-voip@puck.nether.net</A><BR> <B><SPAN style="font-weight:bold">Subject:</SPAN></B> Re: [cisco-voip] Break Mirror on HP MCS</SPAN></FONT><O:P></O:P></P> </DIV><P class="MsoNormal"><FONT size="3" face="Times New Roman"><SPAN style="font-size: 12.0pt"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy">I’ve always just pulled the drive and put in a spare and let it rebuild on our ancient 7835’s. good info here tho.<O:P></O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy"><O:P> </O:P></SPAN></FONT></P> <DIV> <DIV class="MsoNormal" align="center" style="text-align:center"><FONT size="3" face="Times New Roman"><SPAN style="font-size:12.0pt"> <HR size="2" width="100%" align="center" tabindex="-1"> </SPAN></FONT></DIV><P class="MsoNormal"><B><FONT size="2" face="Tahoma"><SPAN style="font-size:10.0pt; font-family:Tahoma;font-weight:bold">From:</SPAN></FONT></B><FONT size="2" face="Tahoma"><SPAN style="font-size:10.0pt;font-family:Tahoma"> cisco-voip-bounces@puck.nether.net [<A href="mailto:cisco-voip-bounces@puck.nether.net">mailto:cisco-voip-bounces@puck.nether.net</A>] <B><SPAN style="font-weight:bold">On Behalf Of </SPAN></B>Jason Aarons (US)<BR> <B><SPAN style="font-weight:bold">Sent:</SPAN></B> Friday, November 03, 2006 10:03 AM<BR> <B><SPAN style="font-weight:bold">To:</SPAN></B> <A href="mailto:cisco-voip@puck.nether.net">cisco-voip@puck.nether.net</A><BR> <B><SPAN style="font-weight:bold">Subject:</SPAN></B> Re: [cisco-voip] Break Mirror on HP MCS</SPAN></FONT><O:P></O:P></P> </DIV><P class="MsoNormal"><FONT size="3" face="Times New Roman"><SPAN style="font-size: 12.0pt"><O:P> </O:P></SPAN></FONT></P><P class="MsoNormal"><FONT size="2" color="navy" face="Arial"><SPAN style="font-size: 10.0pt;font-family:Arial;color:navy">You can’t pull a SATA drive in a MCS-7825 hot, but I’ve pulled many SCSI drives from DL-380s hot.
