Configuring Solaris Systems to See the SAN Disks

This procedure needs to be performed on each of the systems connected to the storage area network (SAN) created by the minnow systems.

Steps

1. Verify that all SAN foundation software packages and patches are installed. This is done through puppet system.

2. Enable Solaris multipathing by editing /kernel/drv/scsi_vhci.conf and setting mpxio-disable="yes". Reboot the system.

3. Use the cfgadm -al to view all disks recognized by the operating system:

   root[bash]@phys-bedge1-2# cfgadm -al Ap_Id Type Receptacle Occupant Condition c0 scsi-bus connected configured unknown c0::dsk/c0t0d0 CD-ROM connected configured unknown c1 scsi-bus connected configured unknown c1::dsk/c1t0d0 disk connected configured unknown c1::dsk/c1t1d0 disk connected configured unknown c2 scsi-bus connected unconfigured unknown c3 fc connected unconfigured unknown c4 fc-fabric connected configured unknown c4::210100e08b3b1fa9 unknown connected unconfigured unknown c4::256000c0ffc84dcd disk connected unconfigured unknown c4::256000c0ffc84ddc disk connected unconfigured unknown c4::266000c0ffe84dcd disk connected unconfigured unknown c4::266000c0ffe84ddc disk connected unconfigured unknown

4. Configure each of the disks with the cfgadm -c configure option, for example:

   root[bash]@phys-bedge1-2# cfgadm -c configure c4::266000c0ffe84dcd

5. Verify that each disk was configured, for example:

   root[bash]@phys-bedge1-2# cfgadm -al |grep c4::266000c0ffe84dcd c4::266000c0ffe84dcd disk connected configured unknown

6. Now run format and you will be able to see the disks. Make sure their path contains /scsi_vhci/*.

7. Configure all disks seen on each of the HBAs. In this design, each disks will have 4 redundant paths. To verify number of paths available run luxadm command.
