Using the Sun StorEdge T3 Array with VxVM

In this mode, the Sun StorEdge Traffic Manager (SSTM) driver or DMP can be used to

handle multipathing. To enable DMP to handle multipathing, the

/kernel/drv/scsi_vhci.conf file must have the MPxIO mode enabled

(mpxio-disable=”yes”).

Note All hosts in the clustered environment must use the same configuration setup for

the T3 array.

Working with VxVM Disks on a Sun StorEdge T3 Array

On a T3 or T3+ array with the c#t#d# naming scheme, use the following procedures to

initialize, remove, uninitialize, or replace VxVM disks.

Note vxconfigd is temporarily stopped and restarted each time the mode of the array

is changed. Keep in mind that data I/O is always operating during this time.

Note You should upgrade the Sun StorEdge T3 and T3+ firmware to 1.17B or later by

installing the appropriate Solaris Operating System patches.

Initializing a Disk on a T3 orT3+ Array in c#t#d# Mode

1. Use Option 20 of vxdiskadm “Change the disk naming scheme” to change the name

scheming mode to enclosure based format.

2. Issue vxdisksetup to initialize the new disk:

# /etc/vx/bin/vxdisksetup -i T30_1

3. Add the disk to a disk group:

# vxdiskadd T30_1

# vxdg -g

dg-name

adddisk disk01=T30_1

4. Use Option 20 of vxdiskadm “Change the disk naming scheme” to change the name

scheming back to c#t#d# mode.
