Memory Disk - Concept ?
Posted: Wed Feb 28, 2024 3:48 am
Recently during an installation I was confronted with the following output:
...
----------------------------------------------------------------------------
There is not enough space on the memory disk.
You must take these steps now to complete this installation:
- Run @SYS$UPDATE:SYS$MD
- Reboot the system
----------------------------------------------------------------------------
...
@SYS$UPDATE:SYS$MD
Duplicate entry for <SYS$LDR>TR$DEBUG.EXE is being ignored
Created memory disk WEB03X$DKA0:[VMS$COMMON.SYS$LDR]SYS$MD.DSK;3
- using 221568 blocks in 1 extent with 25631 spare blocks
- mounted on WEB03X$LDM1550: with volume label MD240598807C
- contains OpenVMS V9.2-1
Can someone explain the concept of a memory disk and why OpenVMS/x86 needs/uses this.
Thanks.
