Zones and SAN

I am planning on creating some zones on a V490 server. I would like to implement the zones feature of Solaris 10. Has anyone placed a zone on a SAN? Is it recommended to place the entire zone on the SAN or leave the sparse root on the internal disk and place just the zones applications on the SAN?

I am curious to what you have done here.
We are thinking of zoning a redundant SunFire 6800 to create a number of zones in one large domain. This way we can have more zones than just four domains. When I did the Solaris 10 for experienced sys admins training, Sun could not actually tell me the best way of attaching SAN storage to multiple non global zones. It did seem as though they had not really thought about it.
They did suggest attaching the SAN storage to the global zone and then presenting the storage as a lofs filesystem and then the zone could attach that way. Considering that zones only have so many rights, it seemed the only thing to do. Considering I have not tried this yet, what did you do?

Non-Global zones and Live Upgrade

Good afternoon,
Trying to find an answer for a question that I have.
Currently we have (2) T5140 servers. One of them is our production Sun Messaging Server and the other is the backup. The zones are SAN-attached disks(currently running on the Production server) and each server is "aware" of them. They are only mounted on one server at a time. My question is, I can do a LiveUpgrade on the backup server (from Solaris10u10 to Solaris10u11) and then detach/export the NGZ from the production system and use "update on attach" to upgrade the NGZ to Solaris10u11. If I don't upgrade the Production Box(Global) to u11 and have to move my NGZ back to it, will "update on attach" rollback the NGZs back to u10?
We have a test system that we will be working through to test using LiveUpgrade without detaching the zones. But wanted to see the feasibility of doing this the way I have it mention in the above paragraph.
Thanks in advance for your help!!

Renaming Zones and Zonesets

Good Day,
Just a basic question. We use 9509's and 9513's for our SAN configuration. If I rename either a zone or an active zoneset does this in any way disrupt the connections using the zone or the zoneset. I want to standardize the naming conventions for our systems to better identify what they serve.
Thanks
Jeffrey

I'm not sure you can just rename the zone and zoneset. I think you may have to edit the current zoneset and add in duplicate zones with the new name, then delete the existing zones, with the old name, and then reactivate the current zoneset to push the change out. As long as there is no change in zone membership, no connectivity should be impacted.
As for the zoneset name, you may have to create a duplicate zoneset with the new name, and all the zones...with the new names...then activate the new zoneset name. Again, this should cause no impact to existing connectivity since the zone members will not be changing.
Hope this helps,
Mike

Zones and Zone Sets

I am trying to create a zone (hard zone - VPF) that is composed of 2 different blades. I would like the fibre attached into these 2 different blades to see each other and anythinf else plugged into the switch. I get an error message saying that I can't do this type of zone because it crosses 2 different blades. Is their a way around this? What am I doing wrong?
Thanks

Any zones not added to the zoneset are effectively unused, so depending on if the zones that are not yet in the zoneset are required, yes you will have to add them in.
However, the WWPNs you have listed do not appear to be using the Cisco recommended format for WWPN Pools (20:00:00:25:B5:xx:yy:zz) so perhaps you are not using pools or these zones are not related to UCS? If they are indeed UCS related zones then yes add them to the zoneset, but consider using the Pools instead if this is so.
My suggestion would be to use all WWPN zones and not mix with interface zones.
On each MDS switch, create a zone that contains only the two WWPNs of the storage controllers, ideally using an easy to identify alias. This guarantees the SAN ports can always see each other. Then, create an additional zone for each UCS blade that contains the blade WWPN from the WWPN Pool as well as the storage zone mentioned above. This allows the vHBA to see the SAN ports.
Here is a reference document you may find helpful.

Firm Zone and Trade off Zone in Scheduling Agreement

Dear All
Please explain in detailed the concept of Firm Zone and Trade off Zone in Scheduling Agreement, and it's effects in MRP run, i.e. If i take a MRP run for a material whci is having firm zone as 30 days and trade off zone as 60 days then what will be the result of MRP. The Material MRP type is VB
Thanks and Regards
Manoj

Hi,
Firm zone is the time frame in which you cannot change your orders (schedule lines) that you have ordered from a vendor in any way (Date change nor quantity change).
Trade off zone is time frame within which you can make changes to your procurement proposals, these changes are acceptable from vendor's side.
These time frames are agreed with the Vendor and then inserted for each scheduling agreement in 'Additional data'.
For your example if you take firm zone 30 days and trade-off zone 60 days, the check starts from current day on which MRP runs. For exampe current day is 1st Oct, all the procurement proposals with delivery date within 30 days that is till 1st September are firm orders, which MRP will not change in any case (You can find such orders with * in front of them in MD04 list). Beyond 1st september they are in trade off zone, in which MRP can modify them.
MRP types (VB in your case) have no correlation with these zones.

I'm trying to burn a dvd from idvd but I keep getting error message, broken assets, but when I check my drop zones and their content there's no error messages on any of them?

I'm trying to burn a dvd from idvd but I keep getting error message, broken assets, but when I check my drop zones and their content there's no error messages on any of them?

Hi
And if You change view - in main "window/view field" so that You see the box-plot structure.
No exclamation marks there either ?
and non at the front page ?
iDVD do not copy Your material - only points to where it is stored. So if on any external hard disks, USB-memories, CDs or DVDs are missing - assetts are broken.
Or if You changed location of any material or directed iPhoto or iTunes or GarageBand to a new Library - Then iMovie/iDVD also get's lost.

Is it possible to patch Global Zone and only specific Non-Global Zones?

Hi Champs,
Is it possible to patch Global Zone and only specific Non-Global Zones? Idea is to patch DEV-zones only on the system & test applications and then patch only the STG-zones on same server!
Not sure if it is possible but just throwing a question...
Cheers,
Nitin

Yes, if you have branded (non-sparse) zone!Branded zones and sparse zones don't have the relation that you imply. In Solaris 10, native zones can be sparse or whole-root (non-sparse, as you say). Zones that are not native zones are branded zones. Branded zones on Solaris 10 include Solaris Legacy Containers, previously known as Solaris 8 Containers and Solaris 9 Containers. That add-on product allows you to run Solaris 8 and Solaris 9 application environments under a thin layer of virtualization provided by the brands framework. solaris8 and solaris9 branded zones can be patched independently of each other and of the global zone.
Solaris 11 has no "native zones" - all zones use the brands framework. The "solaris" brand does no emulation and in that respect is very similar to native zones on Solaris 10. Solaris 11 also provides Solaris 10 Zones via the solaris10 brand. This allows zones or the global zone from a Solaris 10 system to be transferred to a Solaris 11 system and run as solaris10 zones. When running on Solaris 11, solaris10 zones can each be patched independently from each other and the Solaris 11 global zone. Technically, Solaris 11 doesn't have patches - it just has newer versions of packages to which the system is updated.

To break out of a non-global zone and become root user in the global zone

Hi folks
"to break out of a non-global zone and become root user in the global zone through a kernel bug exploit"
Is this possible and has SUN allready a fix/workaround/patch for that?
Cheers

Is it possible there's a bug in the kernel? Sure.
Someone would need to find and identify such a bug before it could be fixed. I've not heard of the discovery of a bug like this. You could check the bug database at www.opensolaris.org.

Can external users change their language, time zone, and locale settings?

Hi,
We’re migrating our hosts from WebEx cloud to our on-prem solution right now (CWMS 1.5.1.323.A).
We’ve learned that CWMS 1.5 does not provide an online address book where hosts could customize language, time zone, and locale settings for their external attendees.
Do external users have any chance at all to change their language, time zone and locale settings individually?
Thank you,
Helge

Hi Dejan,
"external users" are those participants, who do not have an LDAP account in our deployment, since they are not intendet to act as hosts: our stakeholders, partners, customers, clients.
It looks, as if these people would stick to the systems' default language / time zone / locale.
We are wondering if there might be a CWMS-component like this:
https://artcom.webex.com/cmp0307l/webcomponents/widget/preference.do?serviceType=MC&siteurl=artcom&target=Page&backUrl=%2Fmw0307l%2Fmywebex%2Fdefault.do%3Fsiteurl%3Dartcom%26service%3D1
to allow those "extenal" participants to make their adjustments.
Thank you,
Helge

Dedicating physical CPUs to a zone and migrating a Solaris 8 box to a zone?

If I have a machine with a large number of cores (say 24), and dedicate 4 of the CPUs to the zone, psrinfo shows the number of CPU's dedicated to that zone as 4, however, the global zone still shows 24.
Does this mean that if there's enough stuff running in global that it can preempt the stuff running inside the zone? The concern here is that the stuff we want to run in the zone is a bit more critical than in global, so we wouldn't want global to eat up CPU resources of the zone. (I suppose we could repurpose the stuff running inside global and the zone, but then we'd get the reverse isolation issue at some other point.)
The other questions is that there's an old E450 running Solaris 8 and it's got a bunch of stuff installed on it. Would it be possible to somehow convert all the software and data of that E450 into a container or zone and run that on a more modern machine - say a T5420 which runs Solaris 10 (without upgrading the stuff running under the E450 to Solaris 10?)

you can create a flar archive of the entire system and then import it as a solaris 8 zone. if you are doing this on a cool threads system, beware of the processor. it does well with threads. if what you run on the 450 is mostly single threaded or needs a decent cpu, the coolthreads servers are not a good fit.

Time Zone and WLS6SP1 and date time problem

Hi,
We are having our development WebLogic server on a Solaris 2.8 machine. The time
zone of that machine is GMT+5
How ever when we start weblogic in the telnet console, we see this
LD_LIBRARY_PATH=.......
<Jul 5, 2001 1:19:46 AM GMT-05:00> <Info> <Security> <Getting boot password from
user.>
Enter password to boot WebLogic server:
It shows the time as GMT-5.
All our application client machines are at GMT+5.30.So when we update from our
application, the datetime fields go as one day lesser(we have our own serializable
component which does the updating). If i enter Dec 10 2000 in our applet client
and try updating, it goes as Dec 9 2000 into the database.
We tried on a NT machine which had GMT+5.30 as the time zone and it showed GMT+5.30
while starting weblogic. And the dates are updated properly.
Does WLS on Solaris take the timezone,etc from some other place?
Is there any workaround for this?
Thanks in Advance,
Ramkumar

We had the same thing using ReflectionX to connect. Users connection with Telnet
caused weblogic to log with the default timezone ( which included the effects of
daylight savings time ), while those users who connected with Rexec caused weblogic
to use GMT in its logging. This was with weblogic 6.0 sp2

How are you starting up your server? We had a similar situation at our

it was due to the fact that we were using exceed to log into our sun box.
Exceed
was grabbing the users timezone info off of his/her local windows box.
is this what is happening for you?

Jumbo Frames within Solaris 10 zones and multiple interfaces...

We have Jumbo Frames working in the Global Zone, and have the MaxFrameSize=3,3,3 etc...
We also have our AGGR's built correctly and defined aggr1:1 and aggr1:2
the problem is on boot-up, if all the name files (hostname.aggr1 and hostname.aggr1:1) are defined in the /etc directory, then you can't start the zones....?
and if you place the files in the /export/zones/<machinename>/root/etc/ directory, than the interfaces do not start-up automatically..... ?
So If I want all the interfaces in the global zone to be seen by the other zones, and for the interfaces to come live when the zones are booted.... where do the hostname.interface files live....???

Darren:
I understand where you're coming from from a technical perspective. But there is a way you could work around it.
For argument's sake, zones a+b with e1000g0 - e1000g3
From an implementation perspective, what's to stop you from:
e1000g0 / e1000g1 shared between all
e1000g2 plumbed at global, only assigned to zone a.
e1000g3 plumbed at global, only assigned to zone b.
You can certainly have an empty interface file (i.e. cp /dev/null /etc/hostname.e1000g2 ; cp /dev/null /etc/hostname.e1000g3). The interface will plumb but have no IP information configured.
This doesn't give truly exclusive interfaces to either zone, but it operates effectively as though it were.
Warning: I haven't actually tested this, but I see no reason that it wouldn't work.

Whole root or sparse root zones and patching

Hi all,
A while back, I did some cluster patching tests on a system with only sparse root zones, and one with whole root zones...and I seem to recall that the patch time was about equal which surprised me. I had thought the sparse root model mainly is patching the global zone, and even though patchadd may need to run through the sparse NGZ's...that it isn't doing much other than updating /var/sadm info in the NGZ's.
Has anyone seen this to be true or if there are major patching improvements using a "sparse" root NGZ model over a "whole" root model?
thanks much.

My testing showed the same results and I was a bit surprised as well. As I dug into it further my understanding was that the majority of the patch application time goes into figuring out what to patch, not actually copying files around. That work must be done for the sparse zones in the same way as for the full root zones, we just save the few milliseconds of actually backing up and replacing the file.
I suspect there is a large amount of slack that could be optimized in the patching process (both with and without zones), but I don't understand it nearly well enough to say that with any authority.

Whole root zone and packages

I installed in my global zone the "Entire Distribution" of Solaris 10 and some software from Companion CD.
Now I would like install a "whole root zone" with a basic set of packages (like "End User Distribution") and without the packages
from the Companion CD.
I can use pkgrm to delete the unnecessary packages in my whole root zone.
But is there a more elegant way to get a whole root zone only with basic packages?
Regards. P.

The "easy" way would be to do a minimal installation in the Global zone and then install the required services in the local zone.
HTH,
Roger S.
