Non-OS Disk goes Oflline post reboot in VM

Hello Experts,

I am curiously looking for the solution to below issues.

We have created Windows 2012 R2 virtual machines on VMware 5.5 u2 platform.

Added two disk during template deployment, first will be C drive and 2nd will be Swap drive.

Post build, we are adding third disk which will be D drive for Data store.

After handing all VMs over to application team, they have reported the issues that post reboot D disk is going offline and manually need to bring it online.

We have tried setting SAN policy for Online, however, no luck

Also, Interesting thing, If we reboot this server 3-4 time and bring disk online manually, 5th time disk will not go offline post reboot.

Please let me know in case any further information required.

Could someone please help us in finding the root cause.

Thanks in advance.

Now, In order to further test this, We have deployed new Windows 2012R2 OS from ISO with NO customization, and Added disk post build the server.

Now when I reboot it, the newly added disk is going offline.

Also, When I check the disk attribute using Deskpart command, We saw, its Readonly.

How come, the disk configuration is getting changed and going offline on each unexpected reboot ?

We are suspecting it as VMware bugs in version 5.5 u2.

Any comments on this ?

After some more testing we have consolidated below observations.

1. We have added 4 VMDK disk to VM on different SCSI controller.

2. C: and 😧 disk connected to SCSI0:0

3. E: connected to SCSI1:0

4. F: connected to SCSI2:0

5. rebooted VM forcefully and checked apart from C and D drive all drives went offline.

6.Now C: and D:drive changed to SCSI3:0 controller.

7. G: drive added newly on SCSI controller SCSI0:0

8. rebooted VM forcefully and checked apart from C drive all drives went offline.

How come only C disk is coming online and rest of all disk showing connected but OFFLINE.

Any comment from VMware Expert ?

This is now resolved by upgrading Storage box firmware to latest one.
