techdad Windows 2008 clusters 11 Today, 3:42 AM EDT by Lodovico

We have a md3000i and it works great. I have one problem with a windows 2008 cluster. I try and give one node in the cluster a lun from the md3000i and it will see the lun as offline. I can't bring it online or format the new lun. I am not trying to use it as a shared lun in the cluster but as a local drive. Does it have to do with SCSI-3 Persistent Reservation that is required by windows 2008? Does the md3000i support SCSI-3 Persistent Reservation? Thanks for any advice.

captainsniz MD3000i + Seagate ST3500320AS 0 Mar 27 2009, 10:54 PM EDT by captainsniz

We purchased 8 x Seagate ST3500320AS drives about 1 month ago for a Poweredge 2900 series upgrade. After further consideration we decided to just install a iSCSI solution. Our Dell rep told us the trays and drives would work in the MD3000i. After receiving the MD3000i and installing the drives they are showing up as "Unsupported" in the Storage Manager interface. The MD3000i can see the drives, knows the amount of space availabe, knows most everything about the drives but it will not allow us to use them and is flagging them as incompatable. A call to the Dell support confirms these will not work under the current controller firmware version.

Is there a work around? Will upgrading the drives firmware to the latest revison remedy this? Are there plans to support these in the next controller firmware revision? These are one of the most popular SATA drives ever sold by Seagate, I am astonished to find out these are incompatable. Any insight would be great. Thank you in advance...

DenisB-UdeS MD3000i: per-client stats? 3 Jan 30 2009, 9:48 AM EST by matthew_herning

Hello,

I would like to know how I could determine which host is doing the most reading/writing. If I go to iSCSI->View/End iSCSI Sessions, I can see all connections but no access stats. If I go to iSCSI->View iSCSI Statistics, I don't see any sessions, just the local MD3000i ports.

I really would like this info because in the statistics view I can see that almost all I/O is going through controller 0. All my sessions are on VMware esx 3.5 servers with software iSCSI initiators. Each VMware is connected to 2 subnets (on 2 separate switches) and thus have 4 paths to the SAN. Unfortunately it seems it wants to access all LUNs through controller 0 which is not optimal (according to our MD3000i).

Thanks!
