    T4-4 servers virtual disk service for OVM Server for SPARC

    User368268
      Hi All,

      I have to install Solaris Cluster 4.1 on two T4-4 servers Guest Domains with ZFS 7320C as the shared storage. There is also a 10Gbe connectivity among cluster nodes and shared storage. I will be configuring iSCSI LUNs.

      After configuring the virtual network switches for 1Gbe and 10Gbe interfaces, dladm command output is as follows:

      LINK ZONE MEDIA STATE SPEED DUPLEX DEVICE
      net1 global Ethernet unknown 0 unknown igb1
      net9 global Ethernet unknown 0 unknown nxge5
      net0 global Ethernet up 1000 full igb0
      net7 global Ethernet up 10000 full nxge3
      net10 global Ethernet unknown 0 unknown nxge6
      net11 global Ethernet unknown 0 unknown nxge7
      net3 global Ethernet unknown 100 full igb3
      net8 global Ethernet unknown 0 unknown nxge4
      net5 global Ethernet unknown 0 unknown nxge1
      net4 global Ethernet unknown 0 unknown nxge0
      net2 global Ethernet up 1000 full igb2
      net6 global Ethernet up 10000 full nxge2
      net13 global Ethernet up 10 full usbecm0
      net14 global Ethernet up 1000 full vsw0
      net29 global Ethernet up 1000 full vsw1
      net31 global Ethernet up 0 unknown vsw2
      net17 global Ethernet up 100 full vsw3
      net18 global Ethernet up 10000 full vsw4
      net37 global Ethernet up 10000 full vsw5

      Please correct me if I am wrong:

      1. To configure IPMP groups among 10Gbe interfaces and 1Gbe interfaces in the control domain, I need to use the virtual switch devices.

      2. Regarding virtual disk devices for each LDOM, I need to provision from ZFS storage. The Guest domain on one T4-4 server will be clustered with another Guest domain on another T4-4 server. For OS provisioning of Guest Domains, should I create the virtual disk devices from a ZFS pool, file containers or use a disk slice directly. Do the Best practises recommend using file containers on each server?

      Example:

      root@ebsprdb1 # format

      root@ebsprdb1 # ldm add-vdsdev /ldoms/disk-images/vmprdb1.img vol2@primary-vds0

      3. I want to allocate 5 GB for the quorum disk from ZFS storage. I do not intend to use quorum disk for user data; hope the size is enough.
