# mpathadm show mpath-support libmpscsi_vhci.so Uses MPAPI interfaces to show the devices supported by various failover modules.
The information below is for opensolaris/express (snv_73+) folks: The scsi_vhci mpxio code is now visible http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/io/scsi/adapters/scsi_vhci with some of the failover implementations available in the "fops" directory. Failover modules are now supported by separate kernel modules <leningrad:cth> modinfo | grep scsi_vhci 22 7be4c000 1a2a8 189 1 scsi_vhci (SCSI VHCI Driver 1.71) 24 7be78648 1318 - 1 scsi_vhci_f_asym_sun (f_asym_sun 1.8) 25 13f9fc0 3538 - 1 scsi_vhci_f_asym_lsi (f_asym_lsi 1.21) 26 13fd2a8 2630 - 1 scsi_vhci_f_asym_emc (f_asym_emc 1.3) 27 7be67a98 3f8 - 1 scsi_vhci_f_sym_emc (f_sym_emc 1.1) 28 7be79890 588 - 1 scsi_vhci_f_sym (f_sym 1.13) 29 7be7a000 3148 - 1 scsi_vhci_f_tpgs (f_tpgs 1.8) and the failover module plumbed shows up in the device attach messages (the f_sym below). <leningrad:cth> grep f_sym /var/adm/messages | tail -1 Sep 7 02:20:15 leningrad scsi: [ID 799468 kern.info] ssd38 at scsi_vhci0: name g600c0ff0000000000047dd400821c900, bus address g600c0ff0000000000047dd400821c900 f_sym If needed, device specific override is also easier to administer via scsi_vhci.conf. -Chris Vic Engle wrote: > Are the non-Sun Asymmetrical disk arrays supported by Solaris multipathing > S/W documented anywhere? > > Thanks, > Vic > >>From - http://docs.sun.com/source/819-0139/ch_1_prod_oview.html > Symmetrical/Asymmetrical Device Support - The Solaris FC and Storage > Multipathing software support the following disk storage devices. > > All Sun disk storage - both symmetric and asymmetric > All T10/T11 standards complaint non-Sun symmetrical disk devices > Many non-Sun Asymmetrical disk arrays. > > In addition, T10 ALUA support has been added for those asymmetrical devices > that support this T10 standard. > > > This message posted from opensolaris.org > _______________________________________________ > storage-discuss mailing list > [email protected] > http://mail.opensolaris.org/mailman/listinfo/storage-discuss _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
