The value of an all-in-one storage stack

I have written several times about the Solaris Leadvilel storage stack. While debugging a problem on a Solaris 9 host that wasn’t using the Leadville stack, I would wait and wait and wait for various commands to complete. Here is one such example: $ timex /usr/openv/volmgr/bin/scan >/dev/null real 2:25.09 user 0.10 sys 0.45 After migrating […]

Viewing tape devices on Solaris hosts

I have been repairing our backup environment for the past few weeks, and have encountered several nifty tools in the Netbackup volumen management bin directory.

When I configure system logging, I like to configure the syslogd daemon to log […]

Configuring Brocade switches to log to syslog

I manage a number of Brocade switches, and periodically they encounter hardware problems (bad SPFs, faulty cables, etc.). To ensure that I am notified when these problems occur, I like to configure the switches to log errors to a centralized syslog server. Configuring a Brocade switch to use syslog is as simple as running the […]
