Storage Arrays That Are Automatically Detected for Multipathing
The
multipath-tools
package automatically detects the following storage arrays:
3PARdata VV
Compaq* HSV110
Compaq MSA1000
DDN SAN MultiDirector
DEC* HSG80
EMC* CLARiiON* CX
EMC Symmetrix*
FSC CentricStor*
Hewlett Packard* (HP*) A6189A
HP HSV110
HP HSV210
HP Open
Hitachi* DF400
Hitachi DF500
Hitachi DF600
IBM* 3542
IBM ProFibre 4000R
NetApp*
SGI* TP9100
SGI TP9300
SGI TP9400
SGI TP9500
STK OPENstorage DS280
Sun* StorEdge 3510
Sun T4
In general, most other storage arrays should work. When storage arrays are automatically detected,
the default settings for multipathing apply. If you want non-default settings, you must manually
create and configure the
/etc/multipath.conf
file. For information, see Section 7.4.5, “Creating
and Configuring the /etc/multipath.conf File,” on page 56 .
Testing of the IBM zSeries* device with multipathing has shown that the dev_loss_tmo parameter
should be set to 90 seconds, and the fast_io_fail_tmo parameter should be set to 5 seconds. If you
are using zSeries devices, you must manually create and configure the
/etc/multipath.conf
file
to specify the values. For information, see “Configuring Default Settings for zSeries in /etc/
multipath.conf” on page 59 .
Hardware that is not automatically detected requires an appropriate entry for configuration in the
DEVICES
section of the
/etc/multipath.conf
file. In this case, you must manually create and
configure the configuration file. For information, see Section 7.4.5, “Creating and Configuring the /
etc/multipath.conf File,” on page 56 .
