Additional supported RAID features include check consistency for background data integrity, patrol read for media scanning and repairing, 64 logical drive support, up to 64TB LUN support, automatic rebuild and global and dedicated hot spare support. .SH CONFIGURATION .sp .LP The \fBmega_sas.conf\fR file contains no user configurable parameters. Please configure your hardware through the related BIOS utility or the MegaCli configuration utility. If you want to install to a drive attached to a mega_sas HBA, you should create the virtual drive first from the BIOS before running the Solaris install. You can obtain the MegaCli utility from the LSI website. .sp .LP The \fBmega_sas\fR device can support up to 64 virtual disks. Note that BIOS numbers the virtual disks as 1 through 64, however in the Solaris operating environment virtual disks are numbered from 0 to 63. Also note that SAS and SATA drives cannot be configured into the same virtual disk. .SH KNOWN PROBLEMS AND LIMITATIONS .sp .LP The \fBmega_sas\fR driver does not support the LSI MegaRAID SAS 8204ELP, 8204XLP, 8208ELP, and 8208XLP controllers. .SH FILES .sp .ne 2 .na \fB\fB/kernel/drv/mega_sas\fR\fR .ad .RS 30n 32-bit ELF kernel module.
