Mystery drive keep showing up after reboot

Greetings,

I have this drive dka300 labeled as disk19 keep on mounting after a reboot even though I had replaced with a new drive dga19 labeled as disk19 in SYSTARTUP_VMS.COM. I had search the entire SYSTARTUP_VMS.COM and for the old dka300 and find nothing for it. So, when the old drive mounted first, which caused a conflict with the label name.

Where else can this mystery drive hidden and why can't I find it??

Version VMS 7.3-2 on ES45 server.

Please help!! I am going nuts trying to find this dka300 disk device.

Thank you in advance.

Jorge

Jorge,

You can log the entire boot by setting the sysgen-parameter STARTUP_P2 = "VDC"

$ MC SYSMAN STARTUP SET OPTION/VERIFY/OUTPUT=FILE/CHECKPOINTING

The next boot will create the logfile SYS$SYSTEM:STARTUP.LOG

Then you can search the logfile for the MOUNT-command.

Maybe in some other command procedure.
What does
$ sea *.com dka300
say?

Re: Mystery drive keep showing up after reboot

It is not unusual to do some MOUNTs in SYCONFIG or SYLOGICALS, or the MOUNT happens in a completely different procedure that is called from SYSTARTUP_VMS.

Have you watched the system boot sequence to look at what time the mount happens?

If nothing helps, you need to search through all disks, e.g.
$ search sys$sysdevice:[000000...]*.com; dka300

... and if you need to go there, then you should also look for any DEFINE of a name for DKA300.
You just MIGHT have to repeat the search sequence for any such name.
I HAVE been to a site that had about a dozen names defined for some of the disks, which then were used in, eh, "rather creative" ways.

Just in case...

Prooost.

Have one on me.

Re: Mystery drive keep showing up after reboot

Jorge,

guessing what you have. You do a "SHOW DEVICE" and a DKA300 is listed as mounted (system?) with a label of DISK19. But you think there should be no DKA300 on your SCSI bus?

Then you see a new DGA19 mounted (system?) with a label of DISK19? So this is a Fibre Channel connected disk? And DKA300 and DGA19 are both mounted and have the same label?

Is this node in a cluster? Or standalone?

Re: Mystery drive keep showing up after reboot

Jorge,
Is it possible that the dka300 drive once held pagefiles or swapfiles?

If so, the mount might have been included in SYS$SPECIFIC:[SYSMGR]SYPAGSWPFILES.COM, which executes before the startup gets to SYSTARTUP_VMS. This allows page and swapfiles to be installed very early in the startup procedure, particularly if they are not on the system disk.

Re: Mystery drive keep showing up after reboot

I've searched the entire system drive and I could not come up with the drive.

I will continue to look through the pagefile com procedure and "define" procedures if I can find it.

Thanks you all for great suggestions.

Oh by the way, this is a standalone server.

Thank you!!

Re: Mystery drive keep showing up after reboot

C'mon Jorge, tell us more details. Is it that you see a DKA300 from the SHOW DEVICE or, is it you see a (failed) MOUNT of that device during the boot?
