Using the Sun StorEdge A3000/A3500 Array with VxVM

Note The information in this section is current at the time of this printing, but is subject to

change with new versions of the Sun StorEdge A3000/A3500 Array software.

The Sun StorEdge A3000/A3500 Array subsystem with the Sun StorEdge

A3000/A3500Array RAID Manager software is compatible with VxVM 4.0. To ensure

compatibility between the Sun StorEdge A3000/A3500 Array and VxVM, you must do the

following:

◆ The Sun StorEdge A3000/A3500 Array and VxVM installation sequence must be

followed exactly as documented in the section “Installation of VxVM with the Sun

StorEdge A3000/A3500 Array” on page 39.

◆ When VxVM encapsulates a device that has a mounted file system and an entry in the

/etc/vfstab file, VxVM updates the /etc/vfstab entry for that device with the

VxVM device node name. VxVM is not compatible with the Sun StorEdge

A3000/A3500 Array RAID Manager device node naming convention, but it is

compatible with the Solaris Operating System device node naming convention.

Do not use the Sun StorEdge A3000/A3500 Array RAID Manager generated disk

device nodes to encapsulate the Sun StorEdge A3000/A3500 Array devices that have

been configured with file systems and have entries in the /etc/vfstab file, for

example /dev/RAID_module01/0s[0-7] and

/dev/rRAID_module01/0s[0-7].(See the StorEdge A3000/A3500 Array

documentation for the device nodes.)

Instead, use the standard Solaris Operating System device nodes. For example (see

the Solaris Operating System documentation for the standard device nodes):

/dev/rdsk/c3t4d0s0 and /dev/dsk/c3t4d0s0.

For example, you may have an /etc/vfstab entry similar to this:

/dev/RAID_module01/0s0 /dev/rRAID_module01/0s0 /mountpt ufs 2 \

yes -

In this case, use the Solaris Operating System device node that represents this device:

/dev/dsk/c3t4d0s0 /dev/rdsk/c3t4d0s0 /mountpt ufs 2 yes -

◆ Follow the Sun StorEdge A3000/A3500 Array controller error recovery procedures as

documented by the Sun StorEdge A3000/A3500 Array subsystem documentation.

Caution Sun StorEdge A3000/A3500 Array error recovery procedures must be followed

according to the Sun StorEdge A3000/A3500 Array subsystem documentation.

Improper error recovery procedures can cause incompatibility with VxVM.
