How to upgrade the firmware using SSH

The following commands can be used to upgrade the firmware on an HP iLO or iLO2 interface. This procedure is particularly useful when the iLO stops working properly and it's not accessible from the server or via HTTP(S).

Use the following procedure:

    * Use SSH to access the iLO device
    * Log in to the iLO using administrative credentials
    * Type the following command and press enter: "load -source http://ip_address/path/imagename.bin /map1/firmware"
          o  Example: "load -source http://192.168.0.1/ilo2_180.bin /map1/firmware"
    * The interface will download the new image and will reset itself
    * To check the firmware version, log in again using SSH and enter the following command: "show /map1/firmware version"

Solaris: Restricted ftp access

groupadd partsftp
useradd -c "F1 performance project" -d /root/home/partsftp -g partsftp -m -s /usr/bin/false partsftp
svcadm -v enable ftp



Change user's home directory to /u01/network:
Code:
usermod -d /u01/network ftp_user

Then add:
Code:
restricted-uid ftp_user
to /etc/ftpd/ftpaccess file.

Solaris !0: How to start oracle11g with SPFILE in vcs main.cf

Below are task need to be performed.

1.       Edit cvs config file main.cf

Remove parameter Pfile from ORA_oraserver resources

Pfile = /opt/oracle/10.2.0.4_EE/dbs/initDS.ora


2.       Start vcs agent on node1. Clear any FAULT flags on resources.
3.       Start vcs agent on node2.

4.       Perform vcs failover test

bBy default if no pfile defined, vcs will look into $ORACLE_HOME/dbs ffor file below in sequence

  • SPFILEsid.ora
  • SPFILE.ora
  • initSID.ora


FFYI. hastop -all -force was already ran prior this activity

                Owner = oracle

                Pfile = "/opt/oracle/11.2.0.3_EE/dbs/initDS.ora"
