Solaris 10 IPMP and NetApp NFS v4 ACL

Okay here is my issue. I have one T5220 that has a failed NIC. IPMP is setup for active-standby and the NIC fails over on boot. I can reach the system through said interface and send traffic out the failed to NIC (ssh to another server and do a last and I get the 10.255.249.196 address). However the NFS acl I have is limiting to the shared IP address of the IPMP group (10.255.249.196). As that is what it should see. However if it appears that the NFS server is seeing the test IP (10.255.249.197) of the "failed to" NIC.. I added 10.255.249.197 to the NFS acl and all is fine. ifconfig output
e1000g1: flags=219040803<UP,BROADCAST,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,FAILED,CoS> mtu 1500 index 3

DNS sets the host name of the system to 10.255.249.196. But if I leave the ACL as is with the one IP address and wait about 10 minutes after a boot then I am able to mount the NFS share with acl only containing 10.255.249.196.
Here are my hosts hostname.INT files.

I think the IPMP configuration is fine but could be wrong. Any ideas on this? I mean I can add the test IP address to the ACL if need be but that just seems to be a band-aid. Or am I completely nuts and it should work this way.
Thanks,
Ben

Followin up on my post...
The moment I started to add more NFS shares, things slowed down when loggin in big time.
Only way out was to fully open a hole on the sever for every client...
I was able to lock down somewhat the Linux server, to fixed ports, and only open up those (111,2049,656,32766-32769) But on the Solaris server, I can't seem to figure this out...
Any one ?
TIA...

Parameters of NFS in Solaris 10 and Oracle Linux 6 with ZFS Storage 7420 in cluster without database

Hello,
I have ZFS 7420 in cluster and OS Solaris 10 and Oracle Linux 6 without DB and I need mount share NFS in this OS and I do not know which parameters are the best for this.
Wich are the best parameters to mount share NFS in Solaris 10 or Oracle Linux 6?
Thanks
Best regards.

Hi Pascal,
My question is because when We mount share NFS in some servers for example Exadata Database Machine or Super Cluster for best performance we need mount this shares with specific parameters, for example.
Exadata
192.168.36.200:/export/dbname/backup1 /zfssa/dbname/backup1 nfs rw,bg,hard,nointr,rsize=131072,wsize=1048576,tcp,nfsvers=3,timeo=600 0 0
Super Cluster
sscsn1-stor:/export/ssc-shares/share1 - /export/share1 nfs - yes rw,bg,hard,nointr,rsize=131072,wsize=131072,proto=tcp,vers=3
Now,
My network is 10GBE
What happen with normal servers only with OS (Solaris and Linux)?
Which parameters I need use for best performance?
or are not necessary specific parameters.
Thanks.
Best regards.

How to configure IPMP and PFIL/IPF to work together on Solaris 9?

Hi folks,
See the subject regarding my question.
Is there anyone who has ever accomplished this on Solaris 9? If so, what version of IPMP and PFIL/IPF did you use, and what steps did you take to make it work?
I just can't get it to work, I have tried all tips and tricks I could find on the web so far, most of them are regarding Solaris 10.
Many thanks in advance!
RVDL
PS: Duke Stars available.

Not sure what you mean with IPMP, but if you mean active-active loadsharing among more than one interface in the same ifconfig group and subnet monitored by mpathd,
I'm afraid you can't do that with ipf (AFAIK), as the states (from "keep state") are stored per interface while packets may come in and go out unpredictedly and asymetricly on any relevant interface. You must configure active-standby in /etc/hostname.* (or configure 100% static (stateless) rules, i.e. no "keep state" (or pass in&out all TCP with the established flag set)).
I have used active-standby a lot on T1, E450, V480 etc. I compiled ip_filter from Darren's source 3.4 and 4.1
Note: V210/240 and others with the bge-driver may cause problems as the bge-driver is (was) broken, in the way that the stand-by interface isn't 100% stanby (only 99% standby).
Last I checked with snoop it showed sporadic ssh-packets on the stanby-interface making the session hang for a while or timeout. I had to "ifconfig down" the standby interfaces on all V210/240s thus breaking automatic failover.
Active sessions will hang and timeout on failover, but that is ususally only a problem for long-lived sessions like ssh, and no problem for short lived/retry/reconnecting protocol-sessions like HTTP, DNS etc.

Solaris 10 and linux IB

We have a linux cluster running RH5.3 with ofed1.4 using Mellanox MT25418. The cluster is attached to a sun solaris10.7 thumper box. The thumper box export a zfs filesystem via NFS. linux clients mount the filesystem via IPoIB.
Under filesystem I/O load the subnet manager gets repeated path record requests from the sun solaris box. This can bring the SM and the fabric down. Any any one else had issue with solaris IB <-> Linux IB? Any insight into what could be causing the issue?
Thanks,
Mahmoud

PCNFSD for Solaris 9 and 10

Does anyone know where I can get the PCNFSD package for Solaris 9 and 10 for both sparc and x86?

I don't know if pc.nfsd is still available, but there are two better solutions available:
1) Samba
2) The windows services for UNIX which includes an NFS client for Windows..

CLUSTER_INTERCONNECS, IPMP, and Multiple Databases

We are looking to build a 2-node 10g RAC cluster on Solaris 10. We will have two databases in this cluster, in addition to the ASM instance. We want to provide HA for this setup using IPMP.
My understanding is that with Solaris/IPMP, CRS will not be able to validate the health of the secondary private network interface that is identified by the “STANDBY” identifier in ifconfig. This will result in CRS failing to start the Clusterware.
The solution, according to Metalink note 368464.1 is to delete the private network configuration from the OCR via the use of the oifcfg command and then using the CLUSTER_INTERCONNECTS initialization parameter within the database to point to the physical IP used for the interconnect IPMP group.
According to the Oracle docs, if you use the CLUSTER_INTERCONNECTS parameter, then only one database in the cluster can use the IP identified by this parameter; that is, I cannot use the same private IP for the CLUSTER_INTERCONNECTS for all databases.
So if true, with two databases, we are in a bit of a pickle (actually 3, including the ASM instance which will also need to use the interconnect).
Can anyone validate if this is all true, or do I have something wrong?

Thanks for the replies and clarification of the CLUSTER_INTERCONNECTS parameter.
However, I still see that (in that other thread) there seems to be some confusion as per the Metalink note and that JJ's question has not been truly answered.
My understanding, is that with IPMP, you have have 3 IPs per NIC pair (or IPMP group): a physical IP for the IPMP group, and a test IP for each NIC in the pair.
When installing Clusterware, you cannot specify the physical IP for the IPMP group, you can only specify the NIC interfaces, and is it their test IPs that will show up in OIFCFG GETIF.
One of the NICs in the IPMP group will be in standby mode, so when CRS starts up, it cannot validate the health of the standby NIC and will fail. In short, CRS does not KNOW about the physical IP, it only knows the two test IPs. So you don't have HA for the private interconnect using IPMP ( just yet.)
To get around this, you use OIFCFG to remove both private NICs from OCR, and then use the CLUSTER_INTERCONNECTS parameter to store the physical IP of the IPMP group.
That way you will still have HA, as the physical IP will failover to one or the other test IP.
So the question JJ proposed did not get answered: if you remove the private NICs using OIFCFG, how does CRS come up without a private interface in the OCR?
(Or did I get all of this correct?)

I'm new to Solaris 10 and need help to setup ftp server

hello!
I just installed Solaris 10 and I'm trying to setup an ftp server (with ftpd) but I don't know how to do that
my server doesn't need any security or authentication
I'm looking for the default shared files directory
Also wondering what to change in what configuration file...
This OS looks quite similar to some linux I used before but the differencies are big enough to drive me crazy
anyway thanks for your help.
Any advice is welcome :-)

cd /etc/ftpd
vi ftpusers
put a # in front of root and any other users that you wish to be able to ftp
then svcadm restart ftp
If you want to set up an anonymous ftp server, there is a little more involvement

On Solaris 9, its state is either cpu0 or cpu1,
depending on the time I call 'top'. Does that mean
it is actually running on either cpu0 or cpu1?Should be.
What
is the difference between the 'cpu0' state and the
'run' state?A thread can be sleeping (it doesn't have anything to do), or runnable. Although it's runnable, it doesn't mean that it's running right at that instant.
Note that it's difficult to get a good view of the situation with 'top' (or almost any other program). Because whenever 'top' looks, 'top' will always be running, even though it's only running a fraction of the time.
And does it mean all 4 threads are
running/assigned to cpu0 (or cpu1)? No. Each thread is independently executed. But since you only have 2 processors, and since 'top' has to be running when it runs, you'll only ever see your process on at most one other cpu.
You might want to use 'prstat' and 'prstat -L'. The first shows one line per process, the second one line per thread.
On Solaris 10, the state shows 'cpu'. Does it mean
it is running? And does it mean that each thread may
run on a different CPU therefore the state does not
show any particular CPU number? Is it correct that
Solaris 9 assign the CPU on a per-process basis and
Solaris 10 on a per-thread basis?I don't know exactly what top does or doesn't do. You might try 'prstat' instead.
There is no difference at this level between Solaris 9 and 10. All will schedule on a per-thread basis.

How do I install dual-boot Solaris 8 and Solaris 9 on one hard disk ?

I tried to install Solaris 8 and Solaris 9 on same disk using CDs, but
the second installation overwrote the first Solaris which was installed
previoudly on the half-disk size partition of same disk.
How do I install two Solarises on one hard disk ?
Thanks
Yakov

There are no tricks to get Solaris to dual boot on the same drive. Just allocate and pick the free slices not used by the first Solaris install when you put in the second install. Technically speaking there is nothing preventing you from running seven separately bootable Solaris instances on the same drive (one of 8 available slices is overlap -- slice 2) provided you use a swap file on a root partition instead of reserving a whole slice for swap.

Sapinst not started for PI 7.1 on Solaris 1064bit and Oracle10

Installation Master = 51033240_21
Java Component = 51033242
UC Kernel = 51033245
We are doing following to run ./sapinst
1. log on as root
2. set JAVA_HOME, TEMP and DISPLAY
3. go to master DVD and run ./sapinst
The instgui is not showing any error Problematicc sentence structure ./SAPinst is just getting frozen. We used another script ./sapinstgui from the same directory and it shows us some logon screen with port 21212 in the GUI. However, when we try clicking logon it does nothing.
We've ensured that port 21212 or any other port that supposed to be used by SAPinst are not blocked on the firewall or not used by any other application. Host and DNSfiles are also okay. Based on one of the previous forum /etc/nss*.conf files also exist in our PI host. Not sure why the SAPinst GUI is not started.
We've also ensured that we need any new SAPinst support pach from marketplace, however current installation master dvd is the latest one release in March 09 and there are no further patches released by SAP.
Please help if anyone of you have faced this issue before.
Harshal

I tried ./sapinst SAPINST_DIALOG_PORT=<free_port_number> as well as the default port number. Both of them fails.
normally ./sapinst itself should establish all the port automatically that it uses. Which currently is not happening.
Do you want me to copy installation master dvd for Solaris on windows work station from where i'm initiating it through Xmanager session and try running ? The installation master dvd that i'm currenty using is for Solaris platform which meanase ./sapinst is compiled for Solaris, how will it be supported by Windows ?

Need Pre_requisites to install Solution Manager in Solaries 9 and Oracle 10

Hi Administrators,
In my project, we have planned to implement Solution Manager 7.0 in O/S Solaries 9 and Database Oracle 10.2.
We are implementing this Solution Manager in already existing SAP server.
We have server like TSAPNGN, In this server already our QAS ECC 5.0 and QAS BW 3.5 are exist and running in this server.
I need information like, What is the pre_requisites to install SAP application, where already another SAP exist in Server.
Appreciate ur help.
Thanks & Regards,
Jagan.

Hello
There is no difference whether you are installing the Solution Manager on a separate server or an existing server already containing the DEV system. you will get some idea from these Notes
21960 Several instances/systems on one UNIX computer
28392 Two R/3 Systems on one Windows NT Server
322653 DB6: Two or several systems on a host
I think, you should go for Central System installtion for the Solman, with it's own database.
and what do you mean by 'standalone solman' here ?
Just go 'installation and upgrades' -> My application components -> SAP Solution Manager -> Solman 7.0 or EHp1 -> Installation and upgrades
For installation guide
installation and upgrade guiedes -> SAP components -> SAP Solution manager -> Select solman version

Compiler directives to differetiate between solaris 9 and solaris 10

i have an API which makes certain function calls which are different for solaris 9 and solaris 10. i cannot add my own defines, since that would mean that applications too would have to define them.
does the Sun Workshop compiler provide any default directives to differentiate between solaris 9 and solaris 10? something like #ifdef __SunOS_5.10 or something like that?
thanks.

As explained in the C Users Guide, the compiler predefines several macros, one of which is represents the Solaris version number.
The macro name is derived from the output of the commands
uname -s and uname -r, starting with __, connected by _, and with dots replaced by _.
Running on Solaris 9:
% uname -s
SunOS
% uname -r
5.9
The defined macro name is __SunOS_5_9
On Solaris 10 you get __SunOS_5_10
__SunOS_5_9

Solaris 10 and Hitachi LUN mapping with Oracle 10g RAC and ASM?

Hi all,
I am working on an Oracle 10g RAC and ASM installation with Sun E6900 servers attached to a Hitachi SAN for shared storage with Sun Solaris 10 as the server OS. We are using Oracle 10g Release 2 (10.2.0.3) RAC clusterware
for the clustering software and raw devices for shared storage and Veritas VxFs 4.1 filesystem.
My question is this:
How do I map the raw devices and LUNs on the Hitachi SAN to Solaris 10 OS and Oracle 10g RAC ASM?
I am aware that with an Oracle 10g RAC and ASM instance, one needs to configure the ASM instance initialization parameter file to set the asm_diskstring setting to recognize the LUNs that are presented to the host.
I know that Sun Solaris 10 uses /dev/rdsk/CwTxDySz naming convention at the OS level for disks. However, how would I map this to Oracle 10g ASM settings?
I cannot find this critical piece of information ANYWHERE!!!!
Thanks for your help!

You don't seem to state categorically that you are using Solaris Cluster, so I'll assume it since this is mainly a forum about Solaris Cluster (and IMHO, Solaris Cluster with Clusterware is better than Clusterware on its own).
Clusterware has to see the same device names from all cluster nodes. This is why Solaris Cluster (SC) is a positive benefit over Clusterware because SC provides an automatically managed, consistent name space. Clusterware on its own forces you to manage either the symbolic links (or worse mknods) to create a consistent namespace!
So, given the SC consistent namespace you simple add the raw devices into the ASM configuration, i.e. /dev/did/rdsk/dXsY. If you are using Solaris Volume Manager, you would use /dev/md/<setname>/rdsk/dXXX and if you were using CVM/VxVM you would use /dev/vx/rdsk/<dg_name>/<dev_name>.
Of course, if you genuinely are using Clusterware on its own, then you have somewhat of a management issue! ... time to think about installing SC?

Are there differences between Solaris 8 and Solaris 2.6 in the way web pages are displayed for Chinese and Korean text using UTF-8 settings?

A user is running a web application on Solaris Release 2.6 with UTF-8. After the server was updated to Solaris 8, the application is experiencing problems with webpages containing Korean and Chinese text. The encoding is UTF-8. Has anyone experienced this problem? I checked the packages installed on Solaris 8 and they are consistent with what was installed on Solaris 2.6. Could this possibly be a patch-level problem? Thank you.

Hi,
It could be a problem with the necessary patche updation. refer the following FTP site for the Solaris pathces.
connect through the FTP cleint to sunsolve.sun.com
/pub/patches directory contains a lot of patches for solaris.
Find and install the corresponding patch require to solve your problem.
