Apple Mac OS X Server (version 10.2.3 or later) - Manual (Page 606)

606 Chapter 17
SNMP support in Mac OS X Server is turned off by default. To turn it on, use TextEdit or
another application to edit the /etc/hostconfig file on the server. If you turn SNMP on, you
should run the snmpconf command to enter site-specific information, such as system
location and admin email address. Type “man snmpconf ” in a Terminal window to learn
about snmpconf.
You can find SNMP information and tools on the Net-SNMP Home Page, located at
www.net-snmp.com
diskKeyFinder
You can use the diskKeyFinder tool to verify the physical location of a remote headless server
volume that you want to manage. When you specify the bsd file system name for a volume
using diskKeyFinder, you’ll see the drive bay where the volume is located (for example, Bay
2).
To find the bsd file system name of a volume, log in to the server using SSH and type “df -l”.
The output from this command shows the bsd file name and volume path. For example:
Filesystem Mounted On
/dev/disk0s13 /
/dev/disk0s9 /Volumes/Spare3
/dev/disk0s10 /Volumes/Holding
/dev/disk0s11 /Volumes/Spare1
/dev/disk0s12 /Volumes/Spare2
In this example, disk0 has five partitions (also known as slices) named 9, 10, 11, 12, and 13.
If you want to know the physical location of a partition, type, for example, “/System/Library/
ServerSetup/diskKeyFinder /dev/disk0s10”. The tool returns the drive bay number where the
volume is located, for example, “Bay 1”.
Xserve drive bays are numbered in ascending order from left to right. On other Mac OS X
Servers, a drive bay isn’t associated with a disk slice.
Enabling IP Failover
IP failover allows a secondary server to acquire the IP address of a primary server if the
primary server ceases to function. Once the primary server returns to normal operation, the
secondary server relinquishes the IP address. This allows your Web site to remain available
on the network even if the primary server is temporarily offline.
