VxVM Disk Array Configuration Updates

Support for IBM-SDD (Subsystem Device Driver)

VxVM now supports the co-existence of IBM-SDD (vpath) on the Solaris Operating

System; the supported version is IBM-SDD Version 1.4.0.7. SDD supports the multipath

configuration environments in the IBM ESS. VxVM uses enclosure-based names for SDD

devices (vpath).

Support for SDD is provided by the new ASL, libvxvpath.so. vpath

devices/metanodes are represented as vpathN, for example,

/dev/rdsk/vpath12[a-h], where a-h represents partition number or slices.

Using Hitachi Arrays

If you are considering having your host disk reside on an hitachi array, you should first

contact Hitachi Data Systems for the latest information on supported boot disk

configurations with hitachi arrays,

DMP and Hitachi Data Systems 5700E SCSI Disk Array Subsystem

Support

DMP supports the Hitachi Data Systems 5700E Disk Array Subsystem under the

following conditions:

◆ The optional second controller is installed in the array.

◆ One controller is configured as Active and the other controller is configured as Passive

(for improved performance).

◆ The array is connected to two SCSI cards in the host machine.

◆ The array has a firmware version that supports serial numbers in the SCSI inquiry

data and they are configured correctly.
