Newbie to vSAN

Hello,

I am trying to setup a demo, I have a Cisco UCS with 4096 drives, when I try to add a device, it simply crashes, and I have to restart the service to recover. Just need to confirm if 4096 drives are truly not supported or if this is a bug?

3/24 14:00:52.167952 148c IMG: *** ImageDisk_UpdateDriveGeometry: The disk uses unsupported sector size 4096!
3/24 14:00:52.169175 148c debug: *** SaveCrashDump: The program encountered a serious error and may be closed. Crash dump will be created.
Please, save the log file and the crash dump and report the problem to support@starwindsoftware.com

Hi, please try creating HA device, not a disk bridge one.

So you are asking me to create a "Virtual Disk"? I have tried this and the imagefile does create, but I cannot select 512, only 4096. When I try to discover it using the Vsphere iSCSi Software Adapter, the status of target is DEAD. Also I dont need HA this is a standalone server.

I was able to plug in a 2nd HDD that is 512 and created the imagefile and able to see it as ACTIVE for the same target. So it seems 4096 are not going to work. Need someone to confirm.

This is strange as both scripts and GUI worked well for me in the lab.
Try running CreateHA_2.ps1 or CreateImageFile.ps1 which are available at C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell.
Both 4k and 512b devices can be created as HA devices and standalone image files without an issue.
For ESXi iSCSI initiator, as any Linux-based system, the only way to connect the storage is to create a 512b device.

Also, from what I see, you are using a GUI-enabled (might be a trial) license. If it is a trial license, please contact support@starwind.com.
