I/O errors using remote CD-ROM with RSA II under Linux - IBM xSeries

Resolving The Problem

RETAIN tip: H181339

During usage of the remote CD-ROM under Linux, an "Input/Output" error may be generated.

The system is configured with the one or more of the following options:  

• An IBM Remote Supervisor Adapter II, option part number 59P2984, replacement part number (FRU) 02R1654
• An IBM Remote Supervisor Adapter II-EXA, option part number 13N0382, replacement part number (FRU) 73P9246

Notes:

• The IBM eServer xSeries 365 comes with an IBM RSA II as standard.
• The IBM eServer xSeries 445 comes with an IBM RSA as standard, but has an option to upgrade to an IBM RSA II-EXA.

The following operating systems are affected:  

• Red Hat Enterprise Linux, version 2.1
• Red Hat Enterprise Linux, version 3
• Red Hat Professional Workstation 9
• SUSE LINUX Professional 9.0
• SUSE LINUX Enterprise Server 8
  
  Note: This does not imply that the network operating system will work under all combinations of hardware and software. Please see the IBM ServerProven compatibility page for more information.

Follow either the Red Hat Linux, or SUSE LINUX instructions, below:

For remote transfers perform one of the following steps:  

1. Unmount, then remount the remote device in Linux. Try the copy process again.
2. Unmount, then remount the remote device through the RSA-II. Try the copy process again.To unmount the device, close any software applications that are using the device, and perform the following steps:
   1. From a console, type the command:
       
      umount <mount point>
      where <mount point> is the location where the device is mounted such as /mnt/cdrom
      (e.g. unmount /mnt/cdrom)
      
      
   2. Click Unmount from the Remote Session
      
      

   To remount the device, perform the following steps:  
   

   1. Click Mount from the Remote Session
   2. From a console, type the command:
       
      mount <mount point>  
      where <mount point> is the location where the device is to be mounted such as /mnt/cdrom.
      (e.g. mount /mnt/cdrom)
      
      
   3. Note: Unloading the ibmusbasm driver will also provide more reliable behavior.
