Re: unable to mount shadow disk in to shadow set
no specific shadowing patches for 7.3-2 are out yet.
What does an anal/disk/shadow give?
Greetings, Martin

Re: unable to mount shadow disk in to shadow set
Logical Volume Size 8380080 Expansion Size Limit 8589312
The first disk is 8380080 in size but can increase to 8589312.
The second disk is 8378368 in size, thus smaller than the size of the first disk but can not be expanded to the limit size of 8589312.
Check init/lim.
I may be wrong because I'm stuck on 7.3.

Re: unable to mount shadow disk in to shadow set
It is strange that DSA1: with member DRA5: shows:
...
> Total blocks @8378368@ Sectors per track 64
> Total cylinders 8182 Tracks per cylinder 16
> Logical Volume Size @8380080@ Expansion Size Limit 8589312
...
And DRA6: shows:
> Total blocks @8378368@ Sectors per track 64
> Total cylinders 8182 Tracks per cylinder 16
OpenVMS V7.3-2 allows a volume to grow later, provided that the bitmap is large enough. And it allows shadowing of disks with different physical size - I have tried it with a field-test version.
I don't have experience with the volume growth feature, but it looks like both disks have physically the same size, but somehow the 'Logical Volume Size' is bigger than the physical. Honestly, I do not know if it is OK that it displays a bigger value. I can understand if it is smaller, but bigger?
You can try if '$ ANALYZE/DISK_STRUCTURE/REPAIR DSA1:' fixes it.

Re: unable to mount shadow disk in to shadow set
DSA6 has a LOWER expansion limit than DSA1/DRA5.
Like David reported, since 7.3-2 you CAN shadow unequal-sized devices, BUT: the device to be added CANNOT be SMALLER than the one(s) already in the set!!
Do an INITIALIZE of DRA6 with /LIMIT=8589312 (or bigger), and my guess is that you then WILL be able to add DRA6 to DSA1.

Re: unable to mount shadow disk in to shadow set
Please anybody re-read my previous message and tell me if there is an error in my thinking and where it is.
