How do I manage multi

SpecialK — Mon, 02 Nov 2009 20:07:57 -0800

Seemingly arcane Solaris I/O Multipathing (MPxIO) question - how do I remove a physical device on a MPxIO-managed controller? I am a Solaris newbie. I have a Solaris 10u8 machine that is running an attached J4400 and some internal drives. We're using multipathed SAS I/O (enabled via stmsboot), so the device mount points have been moved off from their "normal" c0t5d0 to long strings -- in the case of c0t5d0, it's now /dev/rdsk/c6t5000CCA00A274EDCd0. (I can see the cross-referenced devices with stmsboot -l0.)

Normally, when replacing a disk on a Solaris system, I would run cfgadm -c unconfigure c0::dsk/c0t5d0. However, cfgadm -l does not list c6, nor does it list any disks. In fact, running cfgadm gets me the following:

bash# cfgadm -l /dev/rdsk/c0t5d0

Ap_Id                          Type         Receptacle   Occupant     Condition

/dev/rdsk/c0t5d0: No matching library found



bash# cfgadm -l /dev/rdsk/c6t5000CCA00A274EDCd0

cfgadm: Attachment point not found



bash# cfgadm -l c6t5000CCA00A274EDCd0

Ap_Id                          Type         Receptacle   Occupant     Condition

c6t5000CCA00A274EDCd0: No matching library found

So -- how do I administer and remove physical devices that are in multipath-managed controllers on Solaris 10u8?

Someone should just sell me this already

Building your own RAID, let's talk hardware options... Say the ultimate goal was to make something that looks like N5200 but ran Open Solaris for ZFS. The cheapest I have seen a N5200 is some $600. (even empty). (N7700 uses Linux, and ZFS in FUSE which I would rather not).

So assuming I need something Intel (well, or sparc I guess), 5 bays (or more), SATA.

Perhaps using something like a Q-Box 4 case, which fits 4x 5.25" space.

I should be able to fit something like a Supermicro 5 bay for the drives, which ends with 5 SATA ports. And takes up 3x 5.25" bays. The last bay in the case is half taken by the motherboard.

Now for the main board, seems the latest rage is the Intel Atom (yes?no?) and of that, the Z530 appears to be the embedded chip. Should I look at a ready made board with the chip, or a separate board, that can take the chip.

Of the Mini-ITX boards, I do not see any that directly has 5+ SATA ports:
Mini-ITX boards

So perhaps a 4-port SATA card is needed, or something drastic like using a PATA channel, with SATA adaptor.

I am guessing fanless is probably a good idea for raid? Or should I look at the MITX-6852 which appears to be aimed at embedded as well, and does come with 6-SATA ports.

Any other options to consider? I'm based in Tokyo, so I should be able to get most things, but it does make searching for information a hint harder.

That seems to land around $300, plus LCD display if I can find one to fit in a 5.25" bay.

(SATA Multiplier options are no-go.)

Restricting access to a symbolically-linked path using htaccess

jpoulos — Tue, 14 Oct 2008 07:13:25 -0800

Can I restrict access to a symbolically-linked path using htaccess? I have a Solaris file system that my Apache web server accesses through a symbolic link. I need to restrict access to those files to a select group of users. The rules for access are in a MySQL db, so I'm thinking I can run a cron to regularly generate an htpasswd file. An htaccess file won't work on the remote file system (which isn't running apache), though, will it? Can I add something to my httpd.conf file which will make users authenticate before accessing content on the other side of that symlink?

How can I install Ubuntu alongside XP without being able to boot from a DVD drive?

christopherbdnk — Wed, 26 Dec 2007 16:22:47 -0800

I've recently purchased a new external USB DVD drive, as I do not have a floppy drive or internal CD/DVD drive on this windows PC. I am trying to set it up now for dual-booting Solaris+Ubuntu but, even after updating the BIOS (Phoenix 6.00) I cannot boot a USB drive. First, does anyone have a way I could somehow add USB drivers as a boot option (along with XP), so that I can then add Solaris and Ubuntu (making it four options at boot)? Less useful, is there another BIOS worth trying? (mobo = Abit BD7II i845E updated to most recent bios on Abit's site for this mobo)

Or, is there a way of installing Ubuntu and Solaris from within Windows XP?

thanks
christopher

Need help getting an old Sun Blade 100 to run Solaris 10

northernsoul — Tue, 30 Oct 2007 18:18:04 -0800

Having some trouble installing Solaris 10 on an old Sun Blade 100. Any help? I volunteer some time each week at a local computer for schools program, which takes old computers from government and business and puts them in schools, and saw that they had an old Sun Blade 100 around. Given that they're an exclusively Windows shop and it won't run it, I figured I'd install Solaris 10 with some discs I had around. I'm somewhat of an OS aficionado, so I thought this would be a good way to expand my experience with Operating Systems as well as a chance to finally put these discs to work, since I got them for free from Sun. Using the boot cdrom command, I tried to boot from the DVD drive, however, for some reason the OpenBoot firmware won't recognize the disc as a legitimate install disc (I can't remember the exact message, but it was something to that effect). The install media is a DVD, and it originally had a CD drive, but was swapped out for a DVD drive, if it matters. I've been heard that the first release of Project Indiana is coming out tomorrow. Should I use that instead? I've done some googling on this and haven't come up with any answers, so any help would be appreciated.

Splunking files on Windows boxes

ajp — Tue, 23 Oct 2007 06:04:21 -0800

Getting Splunk running on Solaris 5.8, with log files on Windows boxes. So I've installed Splunk on a Solaris 5.8 box, and now I need to get some data into it. We have a large amount of Windows servers, among other things, with Tomcat logs that I'd love to get into Splunk. People currently remote desktop onto the servers and peruse the logs in Notepad.... ugh!

How best to do this?

It seems that the most obvious way is to mount the Windows drives using SaMBa so Splunk considers them to be locally hosted files (albeit from another server).

Any other way? The less painful, the better.

Let's assume disk space and network bandwidth aren't an issue. I'm just new to Splunk and not too sure of my options. I did RTFM but can't see much specifically about this. I'm sure it's there, somewhere painfully obvious.

AIX and Solaris courses for experienced Linux admin?

tkolstee — Thu, 01 Mar 2007 01:10:45 -0800

Years of Linux experience, but looking for training on Solaris and AIX without having to relearn the basics I've been working with Linux professionally for about 10 years as a system administrator, but have recently taken a position where I'll be administering Solaris and AIX boxes as well. I've worked with other UNIXes in the past (BSD, Mach, SunOS/Solaris, AIX, IRIX, SCO, others) but only at a basic level and feeling my way around things such as package management, installation, and other topics that vary from OS to OS.

I've been offered paid training classes, but most of the courses I've found so far start at the basics, which are pretty similar between all UNIXes. Anyone out there know a vendor that's offering a Solaris or AIX course that won't require me to relearn the parts I already know well?

Learning New Skills Without Access to Hardware

jlstitt — Mon, 08 Jan 2007 10:06:24 -0800

How can I get some experience working with Veritas, SAN/NAS management, backups and more (on Solaris 10) without access to any actual hardware or spending a ton of money? Hi guys. I am interested in learning a few specific skills but I am not currently employed. I have about 10 years managing UNIX and Linux boxes but I am not quite at the hire-able level for an actual UNIX administrator position because I lack experience with some specific that almost everyone uses. Specifically:

Veritas (volume management, backups, SAN)
Websphere / Weblogic
MC/ServiceGuard

I would particularly like to get hands-on experience with these products but they pretty much require expensive hardware (SANs, tape libraries, and so-on) and even keeping my Solaris skills up to date is a challenge.

Classes are so expensive and books really don't give me any experience. I wish I could find a simulated environment to play around with.

Any ideas?

Help the Sun shine!

drstein — Fri, 31 Mar 2006 07:05:04 -0800

I'm going to interview a couple sysadmin candidates in the near future. What are some questions that one should ask a sysadmin candidate that are Solaris specific? Please let me know what the correct answer should be, too. I've found that "How would you use newfs?" is a good one. Help me think of others!

Help me modify the config on a necessarily dissembodied solaris drive

Matt Oneiros — Mon, 27 Mar 2006 20:00:13 -0800

I'm looking for a (preferably) linux based livecd with read and write support for sun UFS. Recently a friend gave me a sun ultra 5. This machine functions perfectly well (albeit headless) and runs numerous services, etc. once it gets running.

Of course, I don't have the appropriate null modem cable to access it via serial console, nor do I have a compatible monitor. Which doesn't bother me too much, as once this is set up the way I'd like it, it'll run headless anyhow.

It currently runs services such as rlogin and telnet, so it should be quite achievable to do all the setup I need over the house's LAN.

The root and core of the problem is this (other than my total lack of experience with Sun machines): There are no user accounts, and I need to enable remote root login anyhow to achieve the various installations and configurations that I need to do before this machine supersedes our tired tired webserver.

Unfortunately /etc/default/login has CONSOLE set to /dev/console. I need to comment this out to enable remote root logins temporarily (one whole # would do the trick of course) but I can't get read/write access from any livecd I've tried thusfar. I can't really see any practical means by which I could make this configuration change at the machine it's self .

Used AIX or Solaris machines

costas — Tue, 08 Nov 2005 09:56:10 -0800

UnixBoxFilter: I need access to an AIX or Solaris box. Does anyone know of a service that will sell VPS-type access to such a beast? Alternatively, what are the best places online to look for used low-end AIX or Solaris workstations (preferrably in the EU). RISC CPUs are a must, so Linux or Solaris x86 can't work here.

Linux or Solaris?

IshmaelGraves — Mon, 31 Oct 2005 07:35:43 -0800

Linux or Solaris? My laptop recently shuffled off its mortal coil, and now I'm faced with a clean new PC to play with. I'd been running Red Hat 9, and I'm trying to decide whether to stick with Linux on the new machine (either Fedora or Ubuntu, probably) or to be adventurous and try the now-free Solaris 10. Most of the documentation I've seen on Solaris 10 has been aimed toward sysadmins; there's not too much commentary from hobbyists. My main questions are: how is hardware support? How hard is it to build something on Solaris which was written for Linux? I've seen references to some sort of translation which is intended to allow Solaris to run Linux applications, but without much detail — does this actually work? Any comments from anyone who's used Solaris would be helpful.
