This has a format similar to the * csh path variable. If the module isn't found in the first directory * it tries the second and so on. The default is /kernel /usr/kernel * * Example: * moddir: /kernel /usr/kernel /other/modules * root device and root filesystem configuration: * * The following may be used to override the defaults provided by * the boot program: * * rootfs: Set the filesystem type of the root. * * rootdev: Set the root device. This should be a fully * expanded physical pathname. The default is the * physical pathname of the device where the boot * program resides. The physical pathname is * highly platform and configuration dependent. * * Example: * rootfs:ufs * rootdev:/sbus@1,f8000000/esp@0,800000/sd@3,0:a * * (Swap device configuration should be specified in /etc/vfstab.) * exclude: * * Modules appearing in the moddir path which are NOT to be loaded, * even if referenced. Note that `exclude' accepts either a module name, * or a filename which includes the directory. * * Examples: * exclude: win * exclude: sys/shmsys * forceload: * * Cause these modules to be loaded at boot time, (just before mounting * the root filesystem) rather than at first reference. Note that * forceload expects a filename which includes the directory. Also * note that loading a module does not necessarily imply that it will * be installed. * * Example: * forceload: drv/foo * set: * * Set an integer variable in the kernel or a module to a new value. * This facility should be used with caution. See system(4). * * Examples: * * To set variables in 'unix': * * set nautopush=32 * set maxusers=40 * * To set a variable named 'debug' in the module named 'test_module' * * set test_module:debug = 0x13 set pcplusmp:apic_panic_on_nmi=1 set apix:apic_panic_on_nmi=1 set dump_plat_mincpu=0 set dump_bzip2_level=1 * * See OS-1361 for dealing with the timer woes. * set pcplusmp:apic_timer_preferred_mode=0 set apix:apic_timer_preferred_mode=0 * for kmem debug uncomment line below * set kmem_flags=0xf set zfs:zfs_nocacheflush = 1 * Set zfs arc max ram to 8 GB * set zfs:zfs_arc_max = 8589934592 * set zfs:zfs_arc_min = 8589934592 * Set zfs arc max ram to 64 GB set zfs:zfs_arc_max = 68719476736 set zfs:zfs_arc_min = 68719476736 * Set zfs arc max ram to 128 GB * set zfs:zfs_arc_max = 137438953472 * set zfs:zfs_arc_min = 137438953472 * smartos tune * disable iSCSI boot * set ibft_noprobe=1 set noexec_user_stack=1 set noexec_user_stack_log=1 set rlim_fd_cur=65536 * Ensure that c-states are disabled set idle_cpu_no_deep_c=1 * 10 GbE Tuning set ip:ip_squeue_fanout=1 * * The traditional (and essentially entirely brain dead) cfgadm(1M)-centric * model of hotpluggin' appears to be basically unnecessary. This tunable * enables the system to create device nodes for newly inserted devices * automatically. See: usr/src/uts/common/io/sata/impl/sata.c:97 * set sata:sata_auto_online=1 * * We want to limit the time spent in any one I/O to 10 seconds for targets * that are not optical. This is still a very long time; our queue depth is * typically 10 or less, and disks will usually fail a command after 2-3s. * So we'd have to have multiple reads of bad sectors queued up to have any * chance of timing out. In practice, timeouts occur because of problems with * disk controllers or firmware, not media errors, and in those cases it will * not help at all to wait longer. * * set sd:sd_io_time=10 * for AoE devices try this one set sd:sd_io_time=20 * Use hires tick to improve some scheduling latency issues set hires_tick=1 |
