[comp.os.vms] Be careful when labeling VMS system disks

BARBE@sdr.slb.COM ("Claude Barbe - SDR - 431 5524", 203) (02/10/88)

After getting a failure message at the very end of the VMS 4.7 update
(which is always frustrating after you lied to the question "Are you
 satisfied with the backup of your system disk"...)

I advise everyone to AVOID putting "." in the system disk label, as in:

	$ SHOW DEVICE SYS$SYSDEVICE

	Device			Device		Error	Volume		 Free
	 Name			Status		Count	 Label		Blocks
	NODE$DUA0:		Mounted		    0  MACHIN4.6	 31684
							      =

If this is the case, then use $ SET VOLUME whatever /LABEL=VMS	! or some 
string that does not contain any file specification separating character.

What happens, is during one of the final automatic reboots, VMS names the
system drive "label$device:" which in the case of ANY4.6$DUA0: leads to
invalid file specifications when RMS parses something like ANY4.6$DUA0:[SYS0.]
and the update fails. I guess the label is used at that time because SCSSYSID
is blank during the VMS update.
