volume shadow on msa1000
two msa1000 (FW 3.36) and two VMS 7.3-1 Hosts.
Problem: MSA1000 only works in active/standby mode, so after rebooting VMS some msa1000 units
appear to VMS over the standby path and could
not be mounted. We have to make a "set device..
/switch/path=pga0" to get access to the disk.
Question: Is it sufficient to make a "set device .../switch/path.." in the system startup file before the "mount/system $1$dga1:
/shadow=$1$dga10" or will the path problem break my shadow set on every reboot ???

Re: volume shadow on msa1000
Are you sure the MSA1000 configuration is correct. ACL added to all units? Correct profile name topology?
You may want to make a mount prosedure that checks availability of all volumes before mounting. Also have a look at MOUNT/POLICY=REQUIRE_MEMBERS to prevent mounting shadowset without all members available.

Re: volume shadow on msa1000
The MSA1000 Systems are redundant (two FC Ports), profile is set to openvms, but no ACL, because all hosts should have access to all ports of the MSA├В┬┤s (standby port in the in case of failover)
If we restrict the access to the active port
with ACL, then the failover will not work.

Re: volume shadow on msa1000
Each Unit and controller assigned a unique ID?
ACL should be OK as long as you add all connections:
show acl
ACL is enabled:
Connection WWPN Units
alpha1_fga0 10000000-C9334CF8 1, 2
alpha1_fgb0 10000000-C9334D52 1, 2
alpha2_fga0 10000000-C9334E82 1, 2
alpha2_fgb0 10000000-C9335306 1, 2
Inaccessible Units: 3, 4, 5
MSA1000_1>> add acl connection=alpha1_fga0 unit=all
Allowing 10000000-C9334CF8 access to unit 1 2 3 4 5.
MSA1000_1>> add acl connection=alpha1_fga0 unit=all
Allowing 10000000-C9334D52 access to unit 1 2 3 4 5.
MSA1000_1>> add acl connection=alpha1_fgb0 unit=all
Allowing 10000000-C9335306 access to unit 1 2 3 4 5.
MSA1000_1>> add acl connection=alpha2_fgb0 unit=all
Allowing 10000000-C9334E82 access to unit 1 2 3 4 5.
MSA1000_1>> show acl
ACL is enabled:

Re: volume shadow on msa1000
Do you have the latest HBA firmware in your Alphaserver?
Do you have the VMS731_MSA1000 patch?
Did you upgrade the firmware in the MSA1000 itself to support VMS?
I have some MSA's that where shipped in Jan 03' and I need to perform all of these steps before I can properly use them.
PGA0 should be the default path on the Alphaservers. Are you sure that you have your primary path on your servers connected to the same fabric as the primary port on the MSA1000? Or do you have these swapped?
VMS really should not care which is active. it should find it without your intervention.
