Mount an ISO image with Solaris

Before you can mount an ISO image with Solaris you need a block device. An ISO image is only a normal file so you need to make it available as a block device. The right tool for this is lofiadm. With lofiadm you can make files available as block devices:

# lofiadm -a /root/sol-10-u10-ga2-sparc-dvd.iso
/dev/lofi/1

VxVM enable failed: License has expired

When you work with Veritas Storage Foundation then you need a valid key. Otherwise you might encounter the following message:

VxVM vxconfigd ERROR V-5-1-1589 enable failed: License has expired or is not available for operation
        transactions are disabled.

vxdisk list: state=disabled

Today I had a strange situation with VxFS. When running vxprint I saw several disks in error state. A closer look at the devices gave me a clue:

# vxdisk list stor1_42
...

Scanning and playing DVB-T

I found a USB DVB-T adapter in my USB spare box and I thought it would be a more or less nice idea to check if it is still running. Since I haven't watch TV in years that could be interesting.The first thing I did was to plug in the adapter and check for firmware messages:

# dmesg| grep firm
[ 4501.549255] dvb-usb: found a 'Afatech AF9015 DVB-T USB2.0 stick' in cold state, will try to load a firmware
[ 4501.550498] dvb-usb: did not find the firmware file. (dvb-usb-af9015.fw) Please see linux/Documentation/dvb/ for more details on firmware-problems. (-2)

IMM

Yesterday I had the 'pleasure' to play with an IMM - one of these dinosaur management processors shipped by IBM. The system was still online so I couldn't do too much. Here is what I could do:

vxprint: NODEVICE

Today I had a broken Veritas mirror. In the middle of the night one path to a storage was missing and when I took look at the Veritas configuration I got the following (output truncated):
