Solaris/SPARC: create a devalias with nvalias
Device aliases are useful in the BootPROM environment be cause they simplify the unwieldly device paths into simple terms like disk and net. There may be cause to create a new device alias on a system as when adding a new or alternate boot device.
Device aliases are created only in the BootPROM (ok prompt). If you want to add an alias for a disk with a path of /pci@1f,0/pci@1,1/ide@3/disk@0,0 use the nvalias command like this:
nvalias disknew /pci@1f,0/pci@1,1/ide@3/disk@0,0
BootPROM versions 3.25 and later support booting from the network. Creating a network device alias is similar:
ok nvalias net /pci@1f,4000/network@2,1:dhcp

Solaris/SPARC: remove a devalias with nvunalias
H3BootPROM device aliases simplify life when booting a SPARC based Solaris system. If change to the system invalidate a device alias, leaving it may complicate matters during panic times when things need to be clear. This recipe describes deleting a deivce alias with nvunalias./H3PTo delete

Troubleshoot SCSI devices with probe-scsi-all
H3If you experience trouble with SCSI devices, one of the best ways to determine if the host hardware can see the SCSI hardware is with probe scsi all. This recipe describes a procedure to use this command./H3PThe probe scsi all is a bootprom command that is not available in the Solaris opera

Configure Solaris for DNS resolution of hostnames
H3Solaris provides extensive control over the means of looking up various name services including DNS. If DNS resolution of hostnames has not been setup, the nsswitch.conf file must be configured in addition to resolv.conf. /H3POnce you have a href="solaris_system_administration_tips96.html

Boot Solaris from CD-ROM to solve problems
H3Some problems cannot be fixed through the operating system, for example not remembering the root password or changes to configuration files that prevent the system from booting. Solaris allows booting from the CD ROM into single user mode which will allow you to mount your filesystems and repai

Check filesystem integrity
H3Errors in a filesystem can prevent a system from booting properly and are commonly caused by improper system shutdown. The fsck (filesystem check) utility can identify and repair errors./H3PTo check and interactively repair filesystem errors on the device c0t0d0s1, run the following command
