stmsboot Conditions

stmsboot enables and disables multipathing on the host, with these conditions:
The utility automatically updates vfstab(4) and dumpadm(1M) configuration to
■
reflect device-name changes.
Note – The system administrator is responsible for modifying application
configuration (for example, backup software, DBMS, and so forth) to reflect updated
device names.
The -L and -l options display the mapping between multipathed and non-
■
multipathed device names, only after changes to the multipathing configuration
take effect; that is, following reboot after invoking stmsboot -e.
ZFS datasets, including ZFS root datasets, are correctly handled by stmsboot.
■
Disables 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 disabling operation to ports attached using the
specified driver.
Updates vfstab and the dump configuration after manually enabling or
disabling multipathing on specific multipath- capable controller ports.
• Prompts you to reboot.
• During reboot, vfstab and the dump configuration update to reflect the
device name changes.
Displays the device name changes from non-multipathing-device names to
multipathing device names on multipath-enabled controller ports.
If multipathing is not enabled, no mappings display.
Displays the device-name changes from non-multipathing device names to
multipathing device names for the specified controller.
If multipathing is not enabled, no mappings display.
