5266.0. "VOLINV on boot of disk w/ SYSUAF, RIGHTSLIST, QMAN" by CHOWDA::GLICKMAN (writing from Newport,RI) Mon Mar 24 1997 15:55

    Hi,
    
    	We seem to get this alot on re-boot on a 5 node VAXcluster
    (3 VAX 7740s, 2 8820s running OpenVMS 6.1 VAX):
    
    	The mount of the disk with the SYSUAF.DAT, RIGHTSLIST.DAT and
    QMAN$MASTER.DAT is early in the startup.  We find that one VAX
    (usually an 8820) has a problem mounting this disk:
    
    %MOUNT-F-NOSHDWMEM, no eligible shadow set members to mount the shadow
    set
   %MOUNT-I-SHDWMEMFAIL, $10$DUA142 failed as a member of the shadow set
    -SYSTEM-F-VOLINV, volume is not software enabled
    %MOUNT-F-SHDWMEMFAIL, $10$DUA142 failed as a member of the shadow set
    -SYSTEM-F-VOLINV, volume is not software enabled
    
    Seems like a timing issue because we find if we shutdown and re-boot
    the node the disk is mounted the very next time.
    
    Anyone else seen this problem? 
    
    Thanks,

	> Anyone else seen this problem? Yes, it's indeed a timing problem. Have a look at sys$examples:mscpmount.com for a procedure which may solve your problem. Jur.
5266.2	What about shadow disks?	CHOWDA::GLICKMAN	writing from Newport,RI	`Thu May 29 1997 18:18`	8
	I'm finally looking at this problem now. Does mscpmount.com deal with disks that are shadowed? I was thinking you want to check on the status of at least one shadow set member to see if you can build the shadow set. You probably need to check on the status of both drives. I would appreciate any inputs on this. Thanks.
5266.3	MSCPMOUNT can handle mounting shadowed disks	XDELTA::HOFFMAN	Steve, OpenVMS Engineering	`Fri May 30 1997 11:46`	15
	: <<< Note 5266.2 by CHOWDA::GLICKMAN "writing from Newport,RI" >>> : -< What about shadow disks? >- Yes, MSCPMOUNT can deal with shadowed disks. Please take a look at the comments in the procedure. You will find the local disk configuration customization requirements, and the run-time options, documented there. In particular, you will need to use the P4 parameter on the MOUNT recursive callback: $ RECURSIVE_CALLBACK MOUNT $255$DUA12 STARWORK01 to contain the appropriate /SHADOW qualifier.
