Mounting disk drives on operating systems such as AIX, HP-UX, and Linux

Some operating systems such as AIX®, HP-UX, or Linux® require you to mount the drive before you can access data on the product disk.

• Mounting the DVD-ROM on AIX

  To mount the DVD-ROM on AIX using the System Management Interface Tool (SMIT), perform the following steps:

  1. Log in as a user with root authority.
  2. Insert the DVD-ROM in the drive.
  3. Create a DVD-ROM mount point by entering the mkdir -p /cdrom command, where cdrom represents the DVD-ROM mount point directory.
  4. Allocate a DVD-ROM file system using SMIT by entering the smit storage command.
  5. After SMIT starts, click System Storage Management (Physical & Logical Storage) > File Systems > Add / Change / Show / Delete File Systems > CDROM File Systems > Add a CDROM File System.
  6. In the Add a CDROM File System window:
     • Enter a device name for your DVD-ROM file system in the DEVICE Name field. Device names for DVD-ROM file systems must be unique. If there is a duplicate device name, you may need to delete a previously-defined DVD-ROM file system or use another name for your directory. The example uses /dev/cd0 as the device name.
     • Enter the DVD-ROM mount point directory in the MOUNT POINT window. In our example, the mount point directory is /cdrom.
     • In the Mount AUTOMATICALLY at system restart field, select yes to enable automatic mounting of the file system.
     • Click OK to close the window, then click Cancel three times to exit SMIT.
  7. Next, mount the DVD-ROM file system by entering the smit mountfs command.
  8. In the Mount a File System window:
     • Enter the device name for this DVD-ROM file system in the FILE SYSTEM name field. In our example, the device name is /dev/cd0.
     • Enter the DVD-ROM mount point in the Directory over which to mount field. In our example, the mount point is /cdrom.
     • Enter cdrfs in the Type of Filesystem field. To view the other kinds of file systems you can mount, click List.
     • In the Mount as READ-ONLY system field, select yes.
     • Accept the remaining default values and click OK to close the window.

     Your DVD-ROM file system is now mounted. To view the contents of the DVD-ROM, place the disk in the drive and enter the cd /cdrom command where cdrom is the DVD-ROM mount point directory.

• Mounting the DVD-ROM on HP-UX

  Because WebSphere Application Server contains several files with long file names, the mount command can fail. The following steps let you mount successfully your WebSphere Application Server product DVD-ROM on the HP-UX platform:

  1. Log in as a user with root authority.
  2. In the /etc directory, add the following line to the pfs_fstab file:

     /dev/dsk/c0t2d0 mount_point pfs-rrip ro,hard

     where mount_point represents the mount point of the DVD-ROM.
  3. Start the pfs daemon by entering the following commands (if they are not already running):

     /usr/sbin/pfs_mountd &    
     /usr/sbin/pfsd 4 & 

  4. Insert the DVD-ROM in the drive, and enter the following commands:

     mkdir /cdrom     
     /usr/sbin/pfs_mount /cdrom 

     The /cdrom variable represents the mount point of the DVD-ROM.

  5. Log out.
  Note: When you attempt to launch Installation Manager from a DVD that was mounted using the CD-ROM file system (CDFS) on an HP-UX operating system, it might fail to launch and point to a log file that contains an exceptions similar to one of the following:

  java.util.zip.ZipException: Exception in opening zip file:

  org.osgi.framework.BundleException: Exception in 
  org.eclipse.update.internal.configurator.ConfigurationActivator.start() 
  or bundle org.eclipse.update.configurator.

  This issue might be caused by Installation Manager reaching the limit of number of descriptors that can be opened on a CDFS-mounted device. This maximum limit is determined by the value for the tunable kernel parameter ncdnode, which specifies the maximum number of CDFS nodes that can be in memory at any given time. To resolve the problem, change the ncdnode system kernel setting to 250. If the problem persists, increase the setting.
• Mounting the DVD-ROM on Linux
  To mount the DVD-ROM on Linux:
  1. Log in as a user with root authority.
  2. Insert the DVD-ROM in the drive and enter the following command:

     mount -t iso9660 -o ro /dev/cdrom /cdrom

     The /cdrom variable represents the mount point of the DVD-ROM.

     Avoid trouble: If you have enabled and enforced Security-Enhanced Linux (SELinux) on your Red Hat Enterprise Linux Version 5 operating system while you are installing the product from the CD, then you must mount the CD with the following option. For more information see Preparing Red Hat Enterprise Linux 5 for installation.

      -o context=system_u:object_r:textrel_shlib_t

  3. Log out.
  Some window managers can automatically mount your DVD-ROM for you. Consult your system documentation for more information.
• Mounting the DVD-ROM on Solaris
  To mount the DVD-ROM on Solaris:
  1. Log in as a user with root authority.
  2. Insert the DVD-ROM into the drive.
  3. If the Volume Manager is not running on your system, enter the following commands to mount the DVD-ROM:

     mkdir -p /cdrom/unnamed_cdrom    
     mount -F hsfs -o ro /dev/dsk/c0t6d0s2 /cdrom/unnamed_cdrom 

     The /cdrom/unnamed_cdrom variable represents the DVD-ROM mount directory and the /dev/dsk/c0t6d0s2 represents the DVD-ROM drive device.

     If you are mounting the DVD-ROM drive from a remote system using NFS, the DVD-ROM file system on the remote machine must be exported with root access. You must also mount that file system with root access on the local machine.

     If the Volume Manager (vold) is running on your system, the DVD-ROM is automatically mounted as:

     /cdrom/unnamed_cdrom 

  4. Log out.
