One of the strange things about the netback Windows GUI is that theres no way to manually inventory a stand alone tape drive. To do this you need a bit of command line knowledge. You’ll mainly need to do this to import media from other servers or media which has been used previously in different backup software. For a stand alone drive the command is as follows, but you can use this on libraries too.

(Standalone drive inventory)
vmphyinv {-n drive_name | -u device_number} [-h device_host]
[-non_interactive] [-verbose]

C:\Program Files\VERITAS\Volmgr\bin>vmphyinv.exe -u 2 -h tapesvr

Proposed Change(s) to Update the Volume Configuration
=====================================================
Logically add new media BE????.
Logically update EMM database, if required.

Update volume configuration? (y/n) n: y

Added new media BE0000 on host tapesvr.
Added media ID BE0000 to EMM database.

C:\Program Files\VERITAS\Volmgr\bin>

You get the device number from the activity monitor->drives screen. Once you run this command Netbackup will start to read the images on the tape, you can see this on the catalog->results screen. Once this is complete the media will appear on the catalog->search screen ready for the phase 2 import.

There is a very annoying issue in Windows, in that it doesn’t let you have more than one partition on a USB drive. There was a workaround for this in XP, but I haven’t been able to get it working in the newer versions. In addition if you have a multi partition USB device and try to use Windows to format it via disk management, you will run into more difficulties where it can only manage the first partition. I can’t help with the first problem, but here is how you solve the second.

Building a template is something you don’t do very often – you tend to do it once and then forget about it. Today I had to make a Windows 2008 R2 template VM for VMware, but luckily I found a handy guide which had done all the hard work for me.

If you use it yourself its worth looking at each setting and asking if it applies to your environment. Some of the settings will probably be set by your GPOs anyway once you add machines deployed from it to your domain, other bits are just slightly anal and unnecessary.

As a side note 2008 R2 only supports 64 bit processors, so make sure your environment is capable fo this before you proceed.

This post on pauldotcom is a handy way of running a command line instruction on every machine in the domain. Ideally you’d use group policy for this kind of thing, but its still useful to know.

I had an issue today with a Dell remote access card (DRAC). This is a card which you get in Dell servers, and is used to perform remote managment. In some situation it can be better than other remote access methods, since it gives you access to the console from boot (so you can view any BIOS messages) and can be used to power on the server remotely. At least thats the idea – in this particular case the card was running very slowly and the remote power on functionality wasn’t working. This isn’t great when you’ve just turned off a server which you don’t have physical access to. Luckily we can solve this by SSHing onto the DRAC and running a reset command. There are actually quite a lot of things we can do from the SSH interface:

To reset the DRAC, we need the racreset command. This will re-initialise the DRAC and after a minute or so everything should be working again

Each month Cisco publish the worldwide CCIE count, which shows how many people have gained certifications over the last month. However it is possible to do a little maths and get a fuller picture – in this case that the numbers are dropping.

The CCIE consists of two parts, the first is a written exam which tests basic knowledge and after that you do a day long lab exam. The lab exam is considered to be the hardest of the two, with most people requiring multiple attempts. Once you have the certification, you just need to pass the written exam every few years to keep it.

Without any input from those who didn’t recertify its hard to work out why they didn’t bother. Change in job role could account for some but it seems unlikely that this would account for the full 61. Is it just that now there are more people with it, the CCIE is less highly regarded?

Every now and then Cisco update their exam tracks, and this time its the CCNP’s turn. Personally, I think the CCNP is hands down the most useful Cisco qualification to have if you work with WAN and LAN networks on a regular basis. The CCNA is too basic to be of much practical use, and the CCIE is great if you do networks full time but today people tend to expect you to know more than one area.

If you are unfamiliar with the CCNP, the previous track consisted of four exams which can be briefly summed up as follows: BSCI (routing), BCMSN (switching), ONT (QoS + wireless), and ISCW (everything else – VPNs, DSL, MPLS, security). The new track is three exams.

The changes are very interesting – I always saw the core of this track as being routing and switching and Cisco seem to be acknowledging that with the first two exams, ROUTE and SWITCH. If you delve a bit deeper into the actual exam topics you can see that they’ve actually cut a lot of the content which isn’t routing or switching out. ROUTE looks to be basically the BSCI exam, with a very small coverage of the VPN and DSL topics from ISCW. SWITCH is the BCMSN with a bit of security. The third exam is TSHOOT, which is aligning with new CCIE track by adding a dedicated troubleshooting element.

Personally I’m 50/50 about the changes. Cisco seem to be trying to make each track very specific with no overlaps (the current CCNP has some overlap with the CCVP, CCSP and CCIP), and while I can see why they would want to do this I think it will produce less rounded engineers at the end of it. If you do the current CCNP you come out of it knowing a lot about routing and switching, and enough about everything else that you can work out most issues after a little research. Its kind of the jack of all trades qualification, which you might expect based on the acronym. With the changes it is turning more into the CCR&SP.  However I do like is the inclusion of the troubleshooting section since just setting equipment up in the first place is only the start of your job, you then have to go and support it.

Luckily I got my CCNP just last year so I’m not affected by the changes, but candidates who are halfway through theirs can either continue with the current track (until July), or substitute BSCI and BCMSN exams they have already completed for ones on the new track. More info on this here

We’ve just had a visit from some Microsoft guys who were going over their new offerings, and on paper it looks very impressive. They seem to be moving to fill in all the holes which previously required 3rd party applications, and it all integrates nicely with existing MS infrastructures.

One of the most interesting things is that they have finally come up with their own AV solution, which uses multiple existing engines plus one of their own. I’m also pretty happy that there is finally an IPS solution (built into TMG, which is roughly the replacement to ISA). They are also jumping on the ‘cloud’ bandwagon and providing outsourced Exchange spam filtering and mail archiving.

All this stuff is either out now or coming out pretty soon, so it will be interesting to see if it holds up to competition once it gets in the wild.

If you have ever had to install a PowerChute agent on a Linux machine, you have probably come across the problem that a Java based GUI is required to configure it.Many Linux servers don’t have a GUI and you may not want to have to worry about setting up Java. If this is the case, we can turn to apcupsd to help with our problem. The example commands here work on RHEL5, if you have a different distribution your files may be in different places.
