Script Execution details

The script will specifically work for Solaris machines with Solaris OS 9 & 10. It is a menu based system providing us with 3 options namely Pre-Checks, Post-Checks and Compare_Pre_Post. It will also provide tar files for Pre and Post checks.  

Both Pre-Checks and Post-Checks will generate files related to the configurations within the server and place it into a folder that is provided as per the script.

Pre-Checks option will be selected before the start of data migration activity to capture configuration details of the Linux machine which will be used at a later stage. Once the storage activity is completed, we will run second option which is Post-checks. 

The 3rd option (Compare_Pre_Post) will be used to verify if there are any changes in the configurations or command outputs. This will help us in identifying details requiring our attention for further troubleshooting.

Interpreting the output of lspci

On Linux, the lspci command lists all PCI devices connected to a host (a computer). Modern computers and PCI devices communicate with each other via PCI Express buses instead of the older Conventional PCI and PCI-X buses since the former buses offer many advantages such as higher throughput rates, smaller physical footprint and native hot plugging functionality. The high performance of the PCI Express bus has also led it to take over the role of other buses such as AGP ; it is also expected that SATA buses too will be replaced by PCI Express buses in the future as solid-state drives become faster and therefore demand higher throughputs from the bus they are attached to (see this article for more on this topic). As a first step, open a terminal and run lspci without any flags (note: lspci may show more information if executed with root privileges): lspci   This is the output I get on my laptop: 00:00.0 Host bridge: Intel Corporation Haswell-ULT DRAM Co

How to get the SAN environment information and statistics on AIX, HP-UX, Linux, Solaris, and Windows

How to get the SAN environment information and statistics on AIX, HP-UX, Linux, Solaris, and Windows Description NetBackup SAN Client is supported on the Linux , Solaris, Windows, HP-UX and AIX operating systems.  These environments provide the initiator device driver which can login to the SAN client media server and mount an pseudo   target device “ARCHIVE PYTHON” so that the backup or restore can be use the fiber transport (FT).  If there is an issue in the SAN environment, it is necessary to get the information/statistics from the SAN fabric for analysis.  The commands below can be used, on the respective operating system, to gather the necessary information. If the outputs show many or steadily increasing error counts, that indicates one or more issues with  the fabric  infrastructure. The issue(s) can be caused by cabling, SFP, san switch, DWDM, HBA or ISL and those components will need to be analyzed and evaluated.  Linux Get the hardware information fo
