Add a new drive from SAN to OpenVMS

I have an rx2660 attached to a P2000 SAN (currently, the SAN is attached through dual redundant HP fiber switches if that matters). I already have 3 virtual disks connected to the server and working. I am trying to add a new larger virtual disk to the machine. The server is not yet in production so a reboot is okay if necessary.

 

$ SHO DEV D

 

RX2660$DKA15: Mounted 0 I64SYS 62010016 359 1
RX2660$DNA0: Online wrtlck 0
$1$DGA100: (RX2660) Mounted 0 DATA1 143197056 1 1
$1$DGA101: (RX2660) Mounted 0 DATA2 234372720 1 1
$1$DGA102: (RX2660) Mounted 0 DATA3 52021312 1 1

 

The new physical drivers are installed in the P2000, provisioned (RAID 1+HS), and mapped (same as the other virtual disks, except I incremented the LUN by 1 to 4). I don't know how to add the drive to OpemVMS. I have tried SYSMAN IO AUTOCONFIGURE but the drive doesn't show.

 

Can someone please help me attach and mount in open vms?

 

Any advice would be most appreciated.

Ok, so I initialized the volume on the SAN without checking the VMS Volume Checkbox. Re-created the volume and SYSMAN IO AUTOCONFIGURE did it's thing.

 

But I still need help with initalizing the drive, mounting, and adding to the startup.

Re: Add a new drive from SAN to OpenVMS

The basics of initialization and mounting disks does get asked around the 'net on occasion, so there are some other discussions to look for.  Most of which will point the reader at the above commands, though there are always variations on the question and the theme and the particular system environment, of course.  

 

Quick overview: INITIALIZE [/various/qualifiers] ddcu: label

 

MOUNT /SYSTEM ddcu: label

 

Disk volumes are typically mounted in the SYS$MANAGER:SYSTARTUP_VMS.COM procedure.  Edit that procedure to add the commands that will be invoked during each bootstrap. 

 

OpenVMS Documentation has the system manager's manuals, and there's a system management utilities manual and a few other resources  are available there that can be useful.

 

There's a book on VMS system management around, as well — I'm one of the authors of that.  

 

In general, having some grounding acquired from skilling the VMS documentation (or the aforementioned book) will help understand the VMS terms and constructs, as well — ddcu: is used as the device name, and the label in the above is what you've assigned to the volume.   The details of DCL and the editor are in the User's Manual, in the VMS documentation.   For a refresher, online HELP is useful.  For this case, see HELP INITIALIZE and HELP MOUNT, and see the documentation, and see resources such as OpenVMS Tips: Disks and the INITIALIZE Command, and OpenVMS Tips: Details and Troubleshooting for the OpenVMS Bootstrap.
