Invoking fx From the Command Monitor

1. Shut the system down into the System Maintenance Menu.

2. Bring up the Command Monitor by choosing the fifth item on the System Maintenance Menu.

3. Identify the copy of fx that you will boot. Some possible locations are: fx in the /stand directory of the system disk or fx on an IRIX software distribution CD in a CD-ROM drive on the local system or on a remote system.

   A single copy of fx is in the /stand directory, but IRIX software distribution CDs contain several processor-specific versions of fx. Booting fx from a CD on a local CD-ROM drive requires a processor-specific copy of sash on the CD, too.

   Table 2-1 shows the versions of sash and fx to use when you are using them from a source that provides several processor-specific versions.

   sash and fx Versions

   Processor Type	sash Version	fx Version
   IP17	sashIP17	fx.IP17
   IP19, IP20, IP22	sashARCS	fx.ARCS
   IP21, IP26	sash64	fx.64

4. Boot fx from the Command Monitor. The command to boot fx depends upon the location of the copy of you are booting.

   • This command boots fx from the /stand directory on the system disk:

     >> boot stand/fx --x

   • This command boots fx from an IRIX software release CD in a local CD-ROM drive, where the CPU type of the system is IP19, IP20, or IP22 and the CD-ROM drive is at drive address 4 on controller 0:

     >> boot -f dksc(0,4,8)sashARCS dksc(0,4,7)stand/fx.ARCS --x

   • This command boots fx from an IRIX software release CD in a CD-ROM drive mounted at /CDROM on a remote system named dist, where the CPU type of the local system is IP21 or IP26:

     >> boot -f bootp()dist:/CDROM/stand/fx.64 --x

5. fx prompts you for each part of the disk name. The default answer is in parentheses and matches the system disk. The prompts are:

   fx: "device-name" = (dksc)

   fx: ctlr# = (0)

   fx: drive# = (1)

   fx: lun# = (0)

   The default device name is dksc, which indicates a SCSI disk on a SCSI controller. (See the fx(1M) reference page for other device names.) The next prompt asks you to specify the disk controller number and the next one the drive address (unit) of the disk. The final prompt asks for the lun (logical unit) number. The logical unit number is typically used by only a few SCSI devices such as RAIDs (an array of disks with built-in redundancy) to address disks within the device. For regular disks, use logical unit number 0.

   For each prompt, press the <Enter> key for the default value or enter another value, followed by <Enter>.

   Once you have answered the prompts, fx performs a disk controller test and you see the fx main menu:

---- please choose one (? for help. .. to quit this menu)----
[exi]t               [d]ebug/                [l]abel/
[b]adblock/          [exe]rcise/             [r]epartition/
fx>

The exit option quits fx, while the other commands take you to submenus. (The slash [/] character after a menu option indicates that choosing that option leads to a submenu.) For complete information on all fx options, see the fx(1M) reference page.
