Linux HP Smart Array Raid Controller

A client has a machine in a DC that has a raid controller and 4 hdd’s set to raid 10, that’s all I was told. I wanted to keep an eye on the hdds, so I needed to install a utility that can monitor and interact with the raid controller.  In my case I have the hp smart array raid controller as you will see in just a bit, you may have a different controller from this one by a different manufacturer, or it may require a different version of the software tool from HP, please check on the HP site linked below before continuing on. There is a chance of serious data loss if you don’t follow common sense practices and MAKE BACKUPS. I needed to do a few things, find out which controller is it, find latest of control utility for it, install said utility and then check on the drives. that isnt always easy, sadly.
First we check who makes this system. dmidecode | grep -A3 '^System Information' Sample result:
System Information
Manufacturer: HP
Product Name: ProLiant DL160 G6
Version:
Second we check lspci to see what controller we have installed. lspci -k|grep -i -A2 raid Sample Result :
04:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)
Subsystem: Hewlett-Packard Company Smart Array P410
Kernel driver in use: hpsa
Now we know we have a HP machine, DL160 G6 to be exact in this case, and the exact rev of the card itself. We need to install the HP provided software for it.  The official HP software page for the information below is here.  However as its laid out, best of luck getting up and running quickly if you follow that page.

You can install package with this link

Now you have the tools needed for the job! so run the utility

CLEANING UP THE ZABBIX DATABASE

My Zabbix database size increased a lot in the last few months and since my disk was running out space, I decided to clean up the old events from the database. Looking at the database tables, the biggest one was  history_uint , which holds the items history data – over 400 millions of records and over 30 Gb of disk space before the clean up. Since deleting the old records from this table directly would be a very slow process, I decided to create a new table and insert the latest records from the  history_uint  table and then just replace the old table with a new one. Since this is not an offical procedure, use it at your own risk. Environment: Zabbix v2.2 MySql 5.1 – InnoDB with  innodb_file_per_table=ON Step 1 – Stop the Zabbix server Step 2 – Open your favourite MySQL client and create a new table CREATE TABLE  history_uint_new  LIKE  history_uint; Step 3 – Insert the latest records from the  history_uint  table to the  history_uint_new table First you need to de

Configuring DHCP Relay service on the FortiGate unit

Configuring DHCP Relay service on the FortiGate unit If the clients are configured to obtain a IP address using DHCP relay, configure the FortiGate server as below: To configure DHCP relay on the FortiGate unit   1. Go to System > Network > Interfaces and select Interface want to configure DHCP relay.   2. Enable DHCP Server in the interface and choose Advanced   3. For Mode, select Relay.   4. In Type select Regular.   5. Select OK.   6. If a router is installed between the FortiGate unit and the DHCP server, define a static route to the DHCP server. Note : Sometimes it is required to specify more than one DHCP relay IP, to allow for the coverage of additional LAN subnets. Although the Web Based Manager (GUI) does not provide an option to configure this, it is possible to set up to 8 IPs from the CLI.       config system interface             edit <REQUIRED_INTERFACE_HERE>               set dhcp-relay-ip <FIRST_IP> <SECOND_IP> ....<EIGHTH_IP&

WAN link load balancing

Hình ảnh
W A N link load balancing In the same way that incoming traffic can be load balanced, outgoing or WAN traffic can also be load balanced and for the same three reasons. 1 .  Reduce the places in the work flow where a single point of failure can bring the process to a halt. 2 .  Expand the capacity of the resources to handle the required workload. 3 .  Have it configured so that the process of balancing the workload is automatic. Often, it can be just as important for an organizations members to be able to access the Internet as it is for the denizens of the Internet to access the Web facing resources. There is now a  WA N Load Balancing  feature located in the  N e t w o r k  section of the GUI (“WAN LLB”). As part of the new WAN Load Balancing feature, the FortiOS 5.2  R ou t e r > Static > Settings  GUI page has been removed. WAN Load Balancing should be used instead of the 5.2  E C M P Load Balancing Method  settings. The 5.2  L i n k Health Monitor  definitions
