Such LUNs cannot be cloned or cloned to a template either. I have constant fail overs due to heavy IO, and the RAW LUNs are in the same HostGroup as the rest of the LUNs, so, they are all configured as "VMWARE" Thereafter, reads and writes go directly to the raw LUN rather than going through the mapping file. I was unaware of this setting, but will consider using this setting next time we run into the issue. try this

No, local RDM’s are not supported. Sponsored Links TrulyMinimal Theme by FlareThemes. I knew it was a partition/format issue, but didn't want to remove the disk or boot with some recovery CD. Partedutil N-Port ID Virtualization Makes it possible to use the NPIV technology that allows a single Fibre Channel HBA port to register with the Fibre Channel fabric using several worldwide port names
Stay up the great work! Lun Reset Command Please note that NFS is not supported as a destination for a RDM disk migration. am using ESX 6.0u2 Reply Edward says: August 19, 2016 at 3:46 am Work great for me ! navigate to these guys These types of software do require communication with the application, thus usually require an agent inside the VM.

You cannot use a RDM (in conjuncture with NPIV) to give a VM access to a VMFS volume. Thanks! Waiting For Timed Out Hb Cormac on June 11, 2013 at 9:05 am said: I think this depends on the BIOS of the adapter. Failed To Reserve Volume Awesome!

Thanks for the guide though, it's very comprehensive. Then I looked in the RDM meta data file but there was nothing directly in there which references the LUN ID of the RDM.

Similar functionality will be available in the ESXi Embedded Host Client when it's available in a later update. Otherwise, all physical characteristics of the underlying hardware are exposed.

I've been involved both with VMware and IBM support, no one could figure out why things failed. Reply Ivo Belitov says: October 23, 2012 at 9:02 am Solved my problem, too!

Vmware Compatibility Guide Is this correct or does the RDM itself only need to be mapped once and it just moves with the guest as vMotion moves the guest ?
THANK YOU!

I’ve been on the hunt for a new house (in Utrecht), have been busy with the VMware Enterprise Solution Provider partnership and did a complete rebuild of my internal Lab Manager
VMware recommends using VMDK virtual disks, unless you are using Microsoft Clustering, in which case you need to use a RDM. With a boot from SAN scenairo using EMC storage groups and adding all of the shared LUNs to each Hosts storage group it becomes difficult to manage Host IDs and LUNs When using Physical Compatibility mode, only the mapping will be migrated (choose ‘Same as Source’ in the Migration Wizard). During relabelling these extra partitions will automatically be destroyed.
It might also be use to create backups of the data on those LUNs in a much more efficient way as compared to traditional backup agents or even VM-based snapshots (using random screenshot below to show where to look ( screenshot removed since it shows too much work information) Right click the naa under identifier and select detach – confirm Now rescan VMFS associates each RDM with its current SCSI device, regardless of changes in the physical configuration of the server because of adapter hardware changes, path changes, device relocation, and so on. In my experience, these still require the ID of the LUN that you are going to use for boot-from-SAN.
When you clone the disk, make a template out of it, or migrate it (if the migration involves copying the disk), the contents of the LUN is into a virtual disk Does anyone know why this setting is even there if it is possible to disable? Mika Reply → habibalby on June 4, 2010 at 07:27 Hello, I'm currently on the process of redesigning my MSA1000 that connected to 4 vSphere hosts and i have MSCS SQL Good luck.

This usually requires physical compatibility mode. For the usual filesystems like NTFS, EXT3, ZFS and NSS, this is no problem at all.
Physical mode is useful to run SAN management agents or other SCSI target based software in the virtual machine. Matt Reply → michael on February 3, 2010 at 14:09 Andy: wow, that is weird.
