Overview

Mounting NFS FS via autofs with options

Procedures

Nfs file systems which are exported via package should be mounted via autofs. Make the entry of Mounitng NFS in auto.direct file with expected option of mount point.

Create a volume group and a File system under Vxvm

Overview

Create a volume group and a File system under Vxvm

Procedures

1.    Initialize disks to be used with VxVM by running the vxdisksetup command only on the primary system. # /etc/vx/bin/vxdisksetup -i c5t0d0 2.    Create the disk group to be used with the vxdg command only on the primary system. # vxdg init logdata c5t0d0 3.    Verify the configuration. # vxdg list 4.    Use the vxassist command to create the logical volume. a.       # vxassist -g logdata make logfile 2048m 5.    Verify the configuration.              # vxprint -g logdata 6.     Make the filesystem.              # newfs -F vxfs /dev/vx/rdsk/logdata/logfile 7.     Create a directory to mount the volume group.              # mkdir /logs 8.     Mount the volume group. # mount /dev/vx/dsk/logdata/logfile /logs 9.     Check if file system exits, then unmount the file system. # umount /logs

HPUX : System Tool for Blade Servers – CPROP

Overview

Procedured describes how to use system tool cprop in blade servers.

Procedures

As CSTM is not supported on blade servers, cprop utility can be used to gather system info. ·               To list the components which can be queried by cprop :-  Check status tab for any error. #-> /opt/propplus/bin/cprop –list  ·         Check summary of the device #-> /opt/propplus/bin/cprop -summary -c Memory  ·         Query the detail view of the device #-> /opt/propplus/bin/cprop -detail -d Memory:5cb50569x139ce0d  Use man cprop;  man cprop_healthtest to get more info about this utility.
