If you want to examine exif information for an image then exiftool by Phil Harvey is excellent at doing this from the commandline. Use: sw_vers In my case: Product Name: Mac OS X Product Version: 10.6.4 Build Version: 10F569 Update: This still works in os x yosemite: Product Name: Mac OS X Product Version: 10.10.2 Build Version: 14C1514 Windows default behaviour is to write to the disk signature of basic disks when they are attached/detected by windows.

This can cause merry hell with iscsi volumes, especially those with existing setups.

I wanted to grab the new package out of jaunty in a sane way.

Running back through the normal commands lead to an error though: # iscsiadm -m discovery –type sendtargets –portal x.x.x.x -P 1 # iscsiadm -m node -l # iscsiadm -m session iscsiadm: Could not get host for sid 1. iscsiadm: could not find session info for session1 iscsiadm: Can not get list of active sessions (6) Turns out it’s a bug, LP #289470.

This appears to allow a single session but you can’t view it’s status.Installing new version of config file /etc/iscsi/...update-rc.d: /etc/init.d/remove: file does not exist * Starting i SCSI initiator service iscsid [fail] * Setting up i SCSI targets iscsiadm: No records found!So, what exactly is the Oracle Clusterware responsible for?It contains all of the cluster and database configuration metadata along with several system management features for RAC.During the installation of Oracle Clusterware, you will be asked for the nodes involved and to configure in the RAC cluster.
