What is the last step that must be performed on a SPARC-based system so that the system boots automatically from the secondary submirror when a primary submirror fails?

  1. use the setenv command to set the auto-boot? variable to false

  2. use the nvalias command to redefine the device alias disk so that it references the primary submirror

  3. use the nvalias command to define a backup_root device alias, which references the secondary submirror

  4. use the setenv command to redefine the boot-device variable so that it references both the primary and secondary submirrors

Question No: 203 – (Topic 2)

You are the system administrator for a system running a business critical database application. To maintain data availability, you are using Solaris Volume Manager and have several two-way mirrors configured. You also have several hot spares created. When creating the hot spare pool, you added devices in this order:

  • a 1.0 gigabyte slice

  • a 2.2 gigabyte slice

  • a 9.8 gigabyte slice

  • a 3.2 gigabyte slice

  • a 6.5 gigabyte slice

Your monitoring software sends you an email indicating that one sub-mirror of a two-way Solaris Volume Manager Software mirror has gone offline because of a hardware error. The sub-mirror that was taken offline was 2.3 gigabytes in size. Which hot spare component will the Solaris Volume Manager software use to recreate the sub-mirror automatically?

  1. The 2.2 gigabyte component

  2. The 3.2 gigabyte component

  3. The 6.5 gigabyte component

  4. The 9.8 gigabyte component
