RE: [ActiveDir] OT: HP disk array expansion

[Derek Harris]

This sounds like the safest way to do it, but you will have some downtime.  I've done it (on a Dell box) the way you described: swapping one disk at a time, and there is downtime that way, too. (in addition to the severe performance hit of the array having to rebuild several times)  From: Blair, James [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 26, 2006 3:52 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] OT: HP disk array expansion James,   Have been in a similar situation on numerous occasions with HP ML350 G3/G4’s. In our case we installed a firewire card and a Lacie drive or utilised the native USB to portable HD and Acronis True Image. We imaged the disks and then pulled them out and put the new ones in and imaged it back, works nicely…This solution even worked for an Exchange server and if it all fails you can simply put the old disks back in and be back where you started…   James   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of James Carter Sent: Thursday, 27 July 2006 7:36 AM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] OT: HP disk array expansion   Hi,   I have a HP ML370 Proliant Server. It currently has 4 x 36GB in a RAID 5 set.   I want to upgrade the disk capacity of this server. I have bought 4 x 300gb disks as replacements.   At present I have 4 x 36GB disks in the server. I was told I could replace one disk in the RAID with a 300GB, let the raid rebuild and do the next disk. Repeat until all of the disks are 300GB and then I can look in the ACU and create a second logical drive that sees all that new space.   Can this be done? Anyone know how long it would take to rebuild? currently there is 90gb used in the current volume.   My other alternative is to buy a Tape Drive, backup, break array, create new array and then restore but this department don't want any downtime.   Anyway shed some light as to which is the best method to take?   thanks James  __________________________________________________ Do You Yahoo!?
