To export directories via NFS, perform the following steps (the following assumes that the central instance host is the NFS server):1. Log on as user root to the NFS server.2. Make sure that your host is configured as NFS server by making sure that the output of the command chkconfig –list nfslooks like:nfs 0:off 1:off […]

The following is an example of increasing the size of a Storage LUN that has an ext3 file system on it. When performing operations like this, perform a backup of the file system first. (The system used for this example is running Red Hat Enterprise Linux Server release 5 (Tikanga), kernel version is 2.6.18-8.el5PAE and

prtvtoc Utility prtvtoc prints the content of the VTOC (volume table of contents). It displays the start/stopcylinder, the size of the partition and the mounted directory. Execute prtvtoc as follows:1. Log on as user root.2. Enter: /usr/sbin/prtvtoc -s <rawdevice> Solaris does not allow track zero on the disk to be part of the raw device

1. Determine the size of the installed RAM with the command:vmstat -P | head -22. Determine the allocated swap space with the command:/usr/sbin/swapon -s3. Determine the required size of the swap space.You can find the minimum swap space requirement in the installation documentation insection Hardware and Software Requirements Check.If possible, you should use an entire

Checking the UNIX Kernel You can check the UNIX kernel with the following UNIX commands: sysconfig -q ipc sysconfig -q proc sysconfig -q vm Compare the output of these commands with the values in the list below. Corrections of the kernel parameters are published in the installation notes. These notes contain the most recent information

1. Log on as user root.2. Create a mount point for the CD-ROM with the command:mkdir <CD-mountdir> (for example, <CD-mountdir> is /sapcd)3. Mount the CD-ROM with the command:mount -dr -t cdfs /dev/rz<n>c <CD-mountdir><n> is the hardware or SCSI address of the CD-ROM (0-6).If the command fails with the message Invalid argument, the kernel is not

When SCSI read and write errors are logged in the syslog, the device number is written in hex. For example: Jun 2 21:13:38 pdb01 vmunix: SCSI: Read error — dev: b 31 0x2b8400, errno: 126, resid: 8192,Jun 2 21:13:39 pdb01 above message repeats 13 timesJun 2 21:13:39 pdb01 vmunix: – dev: b 31 0x2b8400, errno:
