unable to add shadow set member
dsa4324 is a single member shadow set with member $1$dga4324.
I am adding disk $1$dga3324 as a second member.
I have checked size, limit etc..
VMS 8.3 , multinode cluster. Shadowing has been done on this cluster previously.
Please see the attachement.
Thanks in advance for your help.
James

Re: unable to add shadow set member

Re: unable to add shadow set member
I would also try doing an
$ init/sys/limit $1$dga3324: temp
this should set the Expansion Limit and the Logical Volume Size (which should be greater than the Total Blocks on dga4234).
then give it another twirl.
Dave.

Re: unable to add shadow set member
From HELP/MESSAGE INCSHAMEM, here is the list of reasons:
o The shadow set is already fully populated.
o The device being added is not an MSCP device.
o The geometry or other hardware properties of the physical unit do not match those of the other shadow set members.
o The proposed shadow set member is the quorum disk.
o The physical unit is a member of another shadow set.
o The shadow set system disk has the SHADOW_SYS_DISK parameter set to 0 instead of to 1.
Some of those are discounted from what you've posted already, but please recheck them all.
I'd also sanity check your shadowing license. Is it AVAILABILITY or ACTIVITY based?

Re: unable to add shadow set member
I noticed that the DSA device and the disk you are trying to add don't have the same number of blocks. I know this used to be a problem in the past. Was this restriction ever removed from VOLSHAD (I've been away from the VMS world for a few years)? If not, this may be the cause of your issue.
Thanks,

Re: unable to add shadow set member
I found the problem with help from another VMS expert. THe LUN was not presented to all the nodes of the cluster and hence VMS would not allow me since it automagically mounts on all the nodes. ( that is very smart of VMS ! )
thanks you all guys,
