Enabling and Disabling Multipathing in
the Solaris Operating System
This sections describes how to enable and disable multipathing in the Solaris 10,
update 6, operating system.
Use the
stmsboot
command to enable multipathing in the Solaris 10, update 6,
operating system.
stmsboot
manages enumeration of multipath–capable devices
with multipathing; it has these characteristics:
■
Multipathing-
enabled
devices are enumerated under scsi_vhci(7D).
■
Multipathing-
disabled
devices are enumerated under the physical controller.
This section describes the
stmsboot(1M)
administration program for multipathing.
Device Renaming
In the
/dev
and
/devices
trees, multipathing-enabled devices receive new names
that indicate that they are under multipathing control.
■
This means a device has a different name from its original name (after enabling)
when it is under multipathing control.
■
The
stmsboot
command automatically updates /etc/vfstab and dump
configuration to reflect the device names changes when enabling or disabling
Multipathing.
■
One reboot is required for changes to take effect.
stmsboot
Options
TABLE 5-3
describes the options supported by
stmsboot(1M
).
TABLE 5-3
stmsboot
Options
-e [
-D fp
| mpt]
Enables multipathing on all supported multipath-capable controller ports.
• Multipath-capable ports include SAS (mpt[7D]) controller ports.
• Prompts you to reboot.
• During reboot, vfstab and the dump configuration update to reflect the
device-name changes.
• Specifying
-D mpt
limits the enabling operation to ports attached using the
specified driver.
