Mount disks

[cromwoli]

Hi, I am running VirtualBox V6.1 on a Linux Mint host system. I have created a OpenVMS VM from the VMDK file provided. It starts up and runs VMS after I boot DKA0: In the VM machine I have created, I added not only the VMDK but an additional disk which hoped would also be present when I booted VMS up Sadly I don't see anything other than DKA0: How do I mount the other disk as part of the system startup? I have added photographs illustrating how the VM is set up in VIrtualBox, and also what I see when I execute the SH DEV command in VMS.
Any ideas?

I can now mount DKA100 manually by executing a command file I created with the command suggested in it. I have added a line to SYS$SYSTEM:STARTUP.COM to execute this command file in the system startup, then rebooted the system. When the system is up & running again, DKA100 is still not mounted.
I have attached photos to illustrate what I have done.
Any more suggestions will be appreciated.

You are not supposed to edit SYS$SYSTEM:STARTUP.COM - you can add the MOUNT in SYS$MANAGER:SYSTARTUP_VMS.COM or if you need it early in SYS$MANAGER:SYPAGSWPFILES.COM.

I discovered I was editing the wrong command file. I edited sys$manager:systartup_vms.com inserting a line to execute the command file I created to mount dka100. I then rebooted the system. DKA100 is now mounted during the system startup.
I apologise for not following more closely the advice given earlier.
