Failed to create vmfs datastore _ cannot change the host configurations

Hi Team,

We recently installed the esxi 6.7 u3 and we created 2TB lun in dell storage withe iscsi configuration.
When we tried to add the datastore by selecting 2Tb lun .while creating we are getting

Error: Failed to create vmfs datastore _ cannot change the host configuration.

Can you please help in fixing this issue.

Dell server firmware is upto date. Except the bios and lifecycle controller.

Hi @Nani321 ,

Please ensure that the LUN is presented with read-write permissions from storage array.

Additionally, you can also check the /var/run/log/vmkernel.log on ESXi host.

Hope that helps

Hi,

you can use pertedUtil tool in ESX's CLI and check if you can set up any partition on this LUN.

esxcli storage core device list | grep "Display Name\|Devfs"

Use a device path of your LUN.

partedUtil setptbl <Devfs Path> msdos

Look at any error messages.
