Re: Adding OSA devices to a vSwitch...

I see that I can also issue a SET VSWITCH name RDEV origdev newdev. The question is, will adding the second device disrupt the current traffic, or will everything keep running correctly? I think that it should be non-disruptive, but I'm looking for some reassurance I've done this in the past, and it was disruptive in a way that for a few milliseconds the vswitch got stopped. What I did was create an exec with the following commands: /* Add addional osa card */ 'CP SET VSWITCH name DISCONNECT' 'CP SET VSWITCH name RDEV origdev newdev' 'CP SET VSWITCH name CONNECT' As the IP protocol doesn't guarantee packet arrival anyway, so the few lost packets should be retransmitted without anyone noticing the difference.

Re: Question about SMAPI
The SMAPI server requires a directory manager, and DirMaint has been enhanced to work with the new server. From IBM's perspective, there is no reason to not go there just yet. One reason might be that your provisioning product supports the RPC server but does not (yet?) support the SMAPI Socket server. One product in this situation is IBM Director (from IBM). Bob Bolch
Re: dirm needpass no
From DirMaint Support: What they have done is made every command be not prompted for a password. Which of course is not the way DirMaint typically runs. Someone, probably on the listserv, told them in the past they could alter the cmds file to remove them from password authorization. Something which I would typically describe as dangerous but perhaps on their education/test system it is what they want. With this in mind these files are not typical files to be needing tailoring at all. The are tailorable if there is some special case which they seem to have. This is why they are not discussed in the documentation (TAG). In the case of AUTHBY CONTROL this is built when you use the AUTHBY function for BYUSERS. There are several control files in DirMaint which get built because the external command was issued. Therefore there is no need for the customer to be informed of this file. If he would follow the documentation given with the product he is informed of everything he needs to know about. By default DirMaint requires passwords. The way they operate as discussed they are not. However, if the issue a NEEDPASS command which is an optional command it could confuse the issue. What I believe they should have done to give everyone access to all commands by making every command a GENERAL use command. Then the password prompt would not be so confusing. But as long as they know what they have done there is no issue. Just be aware that this could be dangerous. They are giving access to everyone to DASD commands which could be a loaded gun in the hands of the wrong people Colleen M Brown IBM z/VM and Related Products Development and Service Jim Bohnsack [EMAIL PROTECTED] Sent by: The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU 11/14/2007 01:10 PM Please respond to The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU To IBMVM@LISTSERV.UARK.EDU cc Subject Re: dirm needpass no I took a look at doc for 140CMDS and 150CMDS and now I see the Y or N called out for col 35.

(Though he seems to be reading email, so I won't be surprised if he chimes in.) I checked the 140CMDS DATADVH and 150CMDS DATADVH files on the DIRMAINT 11F minidisk on our test VM LPAR which has DirMaint at the z/VM 5.3 level. These two files had mostly Y's in column 35 for the various commands, indicating that a password was required. In production (where we don't need to specify passwords) these two files have all N's in column 35. So I edited the files to specify N's in column 35, and restarted DIRMAINT. Voila! No passwords required. This is without doing anything with GLOBALV on the client side. I checked my GLOBALV files and didn't find NEEDPASS anywhere. Just to be sure I also checked the http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/hcsl3b21/9.43 z/VM 5.3 DirMaint http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/hcsl3b21/9.43 Tailoring and Administration Guide. NEEDPASS is defined in Table 42 as a LASTING GLOBALV variable in pool DVH15 for possible use by DVHCX* and DVHPX* exits in the user's virtual machine (client side). There's no mention of the NEEDPASS global variable being used by anything other than being available for use by these exits.

This is the setting I was referring to which, as your post goes on to note, doesn't work if done SOLELY on the client, because the server still wants a password. So, from the discussion here, I'm getting the idea that even though NEEDPASS NO is remaining set on the client side, upgrading the DIRMAINT server somehow causes it to forget its setting for that same client. And that necessitates yet another NEEDPASS

If you're using SLES, use the DDR starter system install server. The throughput of an internal VSWITCH or GLAN is a vast improvement over FTP to the HMC.

I know the DVD drive in the HMC is a tantalizing morsel, but it is a device that belongs to the HMC, not the CEC. All interactions with the DVD are via the HMC. It would be nice to have a hardware Feature for dual-mode (3422 / FCP) DVD drive in the I/O cage, but my guess is that no one would be willing to pay that much for a DVD drive.

Re: dirm needpass no
Thanks Colleen. Could you please pass this response back to DirMaint Support? This is our production system, and we certainly want to control who can issue DirMaint commands. The question is the best way to do this. In general we want to make things secure, but also easy to use for the few authorized userids. Note that we do NOT give DirMaint authority to all of our users. We give it to a few systems programmers, and a few staff at the Help Desk that are responsible for creating VM userids. To do this, we use the following DirMaint configuration files: AUTHFOR CONTROL AUTHDASD DATADVH (Jim was probably thinking of AUTHFOR CONTROL when he said AUTHBY CONTROL.) We also use RACF to restrict access to 5VMDIR30 11F, the DirMaint primary interface code disk, to only the userids we intend to have DirMaint privileges. With all of that in place to restrict who can issue DirMaint commands, we don't want to also have to have each privileged user respond with a password to use DirMaint.
