Disk Array Conﬁgurations Supported for Use with DMP

Chapter 112

For the DMP functionality to work with the EMC Symmetrix disk array, the following

conditions must be met:

• Common Serial Number Mode should be enabled for all channels that participate in DMP.

This operation should be performed by the EMC Customer Engineer before installing the

VERITAS software packages.

• Disable queue reset on unit attention mode must be set for all channels that participate in

DMP. This operation should be performed by the EMC Customer Engineer before

installing the VERITAS software packages.

• The minimum level of microcode on the EMC Symmetrix should be as shown in the

following table.

Contact your EMC Technical Support Representative for further instructions on conﬁguring

EMC hardware.

See your sales representative for further updates on hardware support.

HP Surestore Disk System FC10

Because of the way LUNs are distributed across controllers by HP-UX, the enable/disable

controller feature of Base-VXVM does not function as expected for the following

conﬁgurations of FC10 disk systems:

• multiple daisy chained FC10 disk systems connected to a single host

• multiple FC10 disk systems connected to a single host through a hub

If the vxdmpadm disable ctlr=ctlr_name command is used for the above conﬁgurations to

disable I/O through a particular controller, I/O can be stopped through paths that were not

intended by the user.
