Configuration for AIX

For Channel-attached 3494s, see AIX Parallel and ESCON Channel Tape Attachment/6000 Installation and User's Guide, order number GA32-0311.

Complete the following steps:

1. Edit /etc/ibmatl.conf.

   Using vi, move the cursor down to the last line, and add a line with three or four fields separated by tabs:

   • Field 1 = 3494 symbolic name (always required)
   • Field 2 = 3494 IP Address (if LAN attached)
   • Field 2 = /dev/ttyX (if serial attached)
   • Field 3 = rs/6000 short hostname (always required)
   • Field 4 = HA3494 IP Address (for high-availability add-ons only)

   Quit out of insert mode and save the file by holding the Shift key while hitting the z key twice.

2. Use SMIT to add a tape drive:

   smitty devices
     Tape Drive
       Add a Tape Drive
         atl   library   LAN/TTY Library Manager Control Point
   

   • The logical name should usually be blank, and the next lmcp number will be used.
   • Library name [F4] will pull up the list from ibmatl.conf (first field).
   • Command timeout should be blank (for defaults).

3. Press the Enter key to define the library.

4. press the F10 key to exit SMIT.

5. Run the following command to bring the /dev/lmcp0 device available and start the lmcpd daemon:

   cfgmgr

Configure the 3494 library for TCP/IP

1. Go to the OS/2 console at the rear of the library.
2. Go to the Commands pulldown.
3. Go to LAN Options.
4. Go to Add a LAN Host.

   1. Select TCP/IP
   2. Alias = Field 3 from ibmatl.conf
   3. IP Address = IP of the RS/6000
   4. Hostname = the host name of the RS/6000

      NOTE: Hostname is the host name as reported by reverse name resolution from the 3494. If this does not match, then you will ALWAYS receive the message, Library is Offline to Host, though this is not the only cause of such a message.

Verify your work

mtlib -l /dev/lmcp0 -qI

Common problems

Configuration problems

• /etc/ibmatl.conf is not configured correctly.
• OS/2 is not configured properly.

TTY problems

• The TTY cable may be disconnected.
• The TTY may not be defined.
• The 3494 may be rebooting.

Network problems

• The network connection could be down. Try entering the following commands:

  From the RS/6000: ping rshostname

  From the 3494: ping 3494hostname

• There is no route to the RS/6000 from the 3494. Open a DOS window on the 3494 and enter:
  
  traceroute rshostname
  
• There is no route to the 3494 from the RS/6000. Run the following command:
  
  traceroute 3494hostname

NOTE: Sometimes the route is picked up by RDP. In this case, using the ping command will open up the connection for some amount of time, then it will fail again. If this happens, have the network administrator of the site check out the network layout, including any bridges or routers in between the RS/6000 host and the 3494 host.
