How to collect XSCF snapshot on M-series servers (M3000 / M4000 / M5000 / M8000 / M9000)
This post describes the various ways to gather diagnostic data from either the XSCF or the domain and XSCF combined. Snapshot stores the collected data on a remote network host or on an external media device, based upon the use of the -T, -t or -d option. To store the collected data on a remote network host using the -t option, the command line must specify a host name (or IP address), a target directory on the remote network host, and the user name of a user on the remote host. When … [Read more...] about How to collect XSCF snapshot on M-series servers (M3000 / M4000 / M5000 / M8000 / M9000)

Most of the time the reason being, the wtmpx file is growing, filling up the /var partition (often part of the root partition). In extreme cases, it may even prevent the possibility of logging in, because utmpx entries cannot be made, and login asks the user to exec login from the lowest level shell. In such cases /var/adm/wtmpx needs to be truncated without causing problems. Using logadm command The most … [Read more...] about Solaris : how to truncate the wtmpx file

How to set OBP Variables from the ALOM/ILOM
It's handy to be able to set various OpenBoot variables from the System Processor (ALOM or ILOM) since sometimes it isn't possible to reach the OBP. From the ILOM Syntax to set any OBP variable from ILOM is as follows : -> set /HOST/bootmode script="value" For example, if you want to disable auto-boot because the system keeps hanging on boot: -> set /HOST/bootmode script="setenv auto-boot? false" If you want to change your console redirection because it was set badly: -> set … [Read more...] about How to set OBP Variables from the ALOM/ILOM
