    Nandinho
      Hi All

      I have a v490 server connected to 2 disk units (3510 storedge) sometime in may we had a problem with them and at tha time we had the following:
      # ./sccli
      Available devices:

      1. /dev/rdsk/c4t600C0FF0000000000B575928EE74EC00d0s2 [SUN StorEdge 3510 SN#0B5759] (Primary)
      2. /dev/rdsk/c4t600C0FF0000000000B577C7138EA2A00d0s2 [SUN StorEdge 3510 SN#0B577C] (Primary)



      but now I have a primary and secondary, and I am triying to work on the secondary and the system is not letting me do anything.
      Please can you help me with this issue?

      now:

      root@nikira # ./sccli
      Available devices:

          Hi.

          For trubleshuting:

          1. Check available path and status:

          luxadm display /dev/rdsk/c4t600C0FF0000000000B575928EE74EC00d0s2
          luxadm display /dev/rdsk/c4t600C0FF0000000000B577C7138EA2A00d0s2

          Check raid status:

          ./sccli /dev/rdsk/c4t600C0FF0000000000B57594FD870C400d0s2 show channels
          ./sccli /dev/rdsk/c4t600C0FF0000000000B57594FD870C400d0s2 show disks
          ./sccli /dev/rdsk/c4t600C0FF0000000000B57594FD870C400d0s2 show events
          ./sccli /dev/rdsk/c4t600C0FF0000000000B57594FD870C400d0s2 show ld
          ./sccli /dev/rdsk/c4t600C0FF0000000000B57594FD870C400d0s2 show channels

            Hi

            I have managed to sort the problem out, by swapping cables, and now are both primary, but something curios "OFFLINE" in luxadm display:

              Hi
              Class primary
              State OFFLINE
              It's not normal. Check /var/adm/messages about errors like OFFLINE ONLINE

              Check FC cable, SPIF on array, port on FC card.


              Regards.

                Hi

                I think its because in one of the interface adapters, with dual ports, I have used one port of the FC card to connect to a NetApp via switch.


                regards

                  Current state- only one path to 3510 present.
