Diskgroup not visible on other node despite using shared disks.

I have a issue where a diskgroup has been created on shared emc disks - all emc disks are visible to both nodes in the cluster, however, a "vxdg -o alldgs list" command on the node where the diskgroup is currently deported, only shows half the disks.

[root@FE1ST54301]-Global# vxdisk -o alldgs list | grep pujnmrsapbi01dg

disk_63      auto:cdsdisk    pujnmrsapbi01dg_01  pujnmrsapbi01dg online

disk_64      auto:cdsdisk    pujnmrsapbi01dg_02  pujnmrsapbi01dg online

disk_65      auto:cdsdisk    pujnmrsapbi01dg_03  pujnmrsapbi01dg online

disk_66      auto:cdsdisk    pujnmrsapbi01dg_04  pujnmrsapbi01dg online

disk_136     auto:cdsdisk    pujnmrsapbi01dg_23  pujnmrsapbi01dg online

disk_137     auto:cdsdisk    pujnmrsapbi01dg_24  pujnmrsapbi01dg online

disk_138     auto:cdsdisk    pujnmrsapbi01dg_25  pujnmrsapbi01dg online

disk_139     auto:cdsdisk    pujnmrsapbi01dg_26  pujnmrsapbi01dg online

 

[root@FE1ST54301]-Global# symvg show pujnmrsapbi01dg | grep disk_

        /dev/vx/rdmp/disk_136s2   00009  64F7  (M)  RW    262155

        /dev/vx/rdmp/disk_137s2   00009  64F9  (M)  RW    262155

        /dev/vx/rdmp/disk_138s2   00009  64FB  (M)  RW    262155

        /dev/vx/rdmp/disk_139s2   00009  64FD  (M)  RW    262155

        /dev/vx/rdmp/disk_63s2    00009  5F88  (S)  RW     56319

        /dev/vx/rdmp/disk_64s2    00009  5F89  (S)  RW     56319

        /dev/vx/rdmp/disk_65s2    00009  5F8A  (S)  RW     56319

        /dev/vx/rdmp/disk_66s2    00009  5F8B  (S)  RW     56319

So on the above machine, we can see the diskgroup contains 8 vxvm disks, and the 8 associated emc devices.

[root@FE1ST54302]-Global# vxdisk -o alldgs list | grep pujnmrsapbi01dg

disk_136     auto:cdsdisk    -            (pujnmrsapbi01dg) online

disk_137     auto:cdsdisk    -            (pujnmrsapbi01dg) online

disk_138     auto:cdsdisk    -            (pujnmrsapbi01dg) online

disk_139     auto:cdsdisk    -            (pujnmrsapbi01dg) online

As you can see on the other machine, it sees only half the disks, even though all the emc devices are visible on both machines which is shown below…

I have tried vxdctl enalbe, and regenerating /etc/vx/disk.info, but still no luck.

Did you manage to resolve this? Are the disks coming from different Arrays? Some are 5F range, others 64?
