The command psrinfo -pv is the command you are looking for. It gives you the number of physical cpus plus the count of virtual processor per physical processor. For example on a V880 it looks like this: The physical processor has 1 virtual processor (0) UltraSPARC-III+ (portid 0 impl 0x15 ver 0x23 clock 900 MHz) The physical processor has 1 virtual ...

It's sunspots. Wrap your printers in magnets. Seriously though - while you may notice some mild signal degradation your wireless equipment should function normally -- at least as an anecdotal data point, none of my equipment showed any problems. I suggest that you look for a more Earthly cause for your wireless woes...

While it is theoretically possible for solar events to affect electronics, the probability is very small for printers, especially two printers in the same area. Bianca Schroeder worked with Google to do a full scale study of the number of DRAM errors caused by cosmic rays and other atmospheric phenomenon and found an incidence rate of between 25,000 to ...

If the tapes are in tar format then you can try tar -tf /dev/sr0 If the files are in cpio format then cpio -ivtB </dev/sr0 may work. If the tapes are in ufsdump format you can try using restore restore -if /dev/st0 then use ls and cd to look at what's on them

I'd never use it. I'm aware of the licensing restrictions around Sun's Java, but if you want things to work, use sun-java6. I've tried setting up tomcat and hudson (for example) using OpenJDK and had a world of pain. It's really not that much harder to specify Sun Java, and it's a considerably better package.

Regarding Backplanes It varies from vendor to vendor, but in general backplanes are not compatible with of the shelf hard-drives. Many need some kind of drive carrier that has the built in interface between the SAS connector and the backplane connector. This is because these kinds of systems are hot-plug, and that requires special bits. Regarding RAID ...

First off, what models are they -- The little one on top looks like a Netra of some kind. The big one is obviously an Ultra Enterprise 4500. Second, quick crash course on Sun hardware, probably applicable to the box on the bottom more than the one on the top: As others have pointed out, if you want to use video you need a 13W3-to-VGA adapter (or a ...

Just don't use the Sun rack!! It really can't be converted. Starting a new project with a round-hole non-standard rack today is irresponsible. Racks are not expensive new. Racks can be purchased used or refurbished, if cost is a concern. If you're going through the steps to rack mount equipment, you may want to future-proof it a bit. A more ...

The EIA-310 standard does have provision for round holed racks, however the Server industry has pretty much stopped supporting them. Square holed racks are far easier to build for and are much more tolerant of slight variances in rail build. Thus, for vendors who have to sell into a market where buyers can have racks from any of a hundred suppliers it makes ...

Iain gave a part of the answer, but it isn't complete. Here comes advice on how to read unknown tapes on a linux host: Blocking factor You need to know what blocking factor has been used, unless the (possibly ancient) drive uses a fixed block size. First, you'll have to set the drive to use soft blocking factor: # mt -f /dev/nst0 setblk 0 Then you'll ...

Sparc IV processors enjoy a supercomputer-like memory bus that has only been approached or equaled by the introduction of Core i7. As a result the are good at churning through large quantities of data (think database, large analysis) at a consistant rate. Actual Dhrystone benchmarks usually trail Intel. UltraSPARC-T1 processors plow through parallel ...

Normally, you have to turn the key to prevent this. Check for the key position. else: Disabling Sun keyboard abort sequence The default keyboard abort sequence on a Solaris system is sent with the L1-A or STOP-A keys pressed together on an attached Sun keyboard, or the BREAK signal on the serial console. Inserting or unplugging a keyboard on a running Sun ...

Searching about has led me to the qmod utility. I've done a simple test of qmod -d QUEUENAME.q@MACHINENAME and this seems to be working, although I haven't actually tried it with jobs running. The qstat output is changed to indicate that the node is disabled - a "d" flag appears. qmod -e QUEUENAME.q@MACHINENAME will enable the machine again. ...

The 7000 series gave us lots of problems in the beginning. We had failover not working, remote replication failing with >1TB jobs and the web interface locked a lot. This was on a 7410 cluster with the 2009.x firmware versions. We even took it out of production and made the case with Sun at the time that we were seriously considering dumping it and never ...

Unfortunately, I have no extra insight on the reason why the jumper wouldn't work, but you can reset the password using ipmitool, with the commands: ipmitool user list 1 <Find the appropriate user id in the returned list> ipmitool user set password <userid> <newpassword> Adapted from How to reset iLOM root password on Sun/Oracle X ...

The serial management console will probably be your best bet. Last time I did this I used a USB-to-serial adapter with my normal laptop sat on top of the server. They're slow, so try to avoid -v command line options, but they'll work when other methods fail.

All of the servers you list have an ALOM which can be accessed via the SER-MGT port. This is an RJ45 serial connection. You'll need to get or make a suitable cable. You'll also need to get familiar with the ALOM for each machine. THe Docs are available on the Oracle website still.

Its true, the sun-java6-jdk has gone, due to licensing issues its not available from apt. See: https://help.ubuntu.com/community/Java Describes work arounds.

If I assume you are talking about square post hole rack rails, the way to remove them is less than obvious and almost invisible when they are installed in rack. There are 2 ways to remove them. Access above/below: In this case there is a spring loaded tab that faces the outside of the racks that can be pressed in if you have smallish hands or wide racks. ...

Depending on how you're doing the adding, there are a couple of ways of doing this. MemberOf is a multi-valued attribute. If you're using an LDIF file, or direct LDAP syntax, you just add multiple MemberOf statements: Department: Human Resources MemberOf: CN=AAA,OU=BBB,DC=CCC,DC=DDD MemberOf: CN=AAB,OU=BBB,DC=CCC,DC=DDD MemberOf: CN=ABC,OU=CDE,DC=CCC,DC,DDD ...

The GNU version of ls can be found in the coreutils package at Sun Freeware.

Rip the CD to ISO then use ILOM virtual media to install. Side note: explaining how lazy you are isn't going to score points with the SysAdmins here.

use the equivs package to create a dummy package which provides the missing java6-runtime dependency, which will make dpkg/apt think that this dependency is satisfied. Here are some basic instructions on the debian wiki. Also note that openjdk-6-jre is the free version of java, which is still available from ubuntu, and generally just works, and might be a ...

NAT on VirtualBox is not that good you might want to try Host-only with some "host natting" as explained in this article : http://akutz.wordpress.com/2009/08/20/building-a-better-os-x-firewall-or-how-i-solved-the-nat-problem-for-virtualbox/

As far as i can read only ALOM CMT supports snmp traps directly. Anyway you could do it passing through sunmc agent, as stated here: http://wikis.sun.com/display/ASRSO/Sun+T1+T2 (read Advanced Lights Out Manager (ALOM) Requirements) Hope this helps.
