RE: Clearcase and Netapp

Hi Kumar, We are CC users on NetApps. It works great! Question 1. I would say yes, as it means you can set a no quotas style volume and not worry about your CC data swallowing up all your available resource. Question 2. As per the info above I would say no. Keep the CC data separate. There seems to be no official reason for this, but it make managing it all easier. Question 3. Locking the vobs is relatively easy. We use a Perl script that another message board regular and employ of our company devised for us. It simply runs a lock command on all vobs, runs a snapshot command on the filer volume then unlocks all the vobs. The snapshot can then be backed up at leisure. I will ask him if he thinks this is something he could publish. This kind of adds weight to the argument for having a separate volume. You are not wise to do incremental backups of CC data. There is no real way to restore an incremental, so full backups are required, and this means nightly full backups of the whole CC data. If you are chucking other data in there as well this means full nightly backups of ALL your data! CC data grows fast, so will be a big lump on its own. Hope this helps. There are great white papers on NOW that cover this too.

Dinostor TapeServer
by Holland, William L 27 Jun '03

27 Jun '03

Anyone out there using this product? (http://www.dinostor.com). If so, with which tape library and which backup software package? Since I'm setting up my NetApps from scratch and have no FCP equipment I would really like to build a GbE solution. However, the boss wants LTO2 and so far no one has a GbE solution for LTO2 -- most seem to be several months away. Also, I don't want to dedicate a tape library to one particular NetApp as I expect we will get a couple more in the not so distant future. Thanks again.

Separate volume for vobs Separate volume for views Other volumes for other data. Year 3 of all 4 pools on a NetApp used for vobs and views.

It just makes things more complicated to troubleshoot. c) Yes. d) It depends on what other data you have on that same volume. If it is just home directory or just files then it really doesn't matter. You have to lock the VOB, snapshot the volume where the VOB data is and then unlock the VOB. Most of this is covered in here: http://www.netapp.com/tech_library/3111.html Let me know if you have more questions.

RE: Question about mirroring
by jeff.mery＠ni.com 27 Jun '03

Actually, this would require at least one trust to be established between NTDom1 and NTDom2. NTDom2 must be trusting of NTDom1 in order for FilerB to see the Global Groups in NTDom1. If there's no trust, then there isn't a way to see/use the groups in the other domain. However, once you create the trust, you shouldn't have to do anything else (i.e. no local groups to manage). FilerB should be able to see all groups in NTDom1. Now assuming that this is for disaster recovery, there is a small problem. Let's say Mr. Stay-Puft takes out SiteA. NTDom1 no longer exists so FilerB is unable to resolve SID information on NTDom1 global groups (the effect is no access for anyone with an account in NTDom1). A simple, but effective remedy for this would be installing a BDC for NTDom1 one at SiteB. When Mr. Stay-Puft comes around, all you have to do is promote the BDC for NTDom1 at SiteB to the PDC for NTDom1. FilerB won't have any problems in this case.

Then add users from NTDom1 to the FilerA groups. These groups would, of course, have to be documented so that they can be created on FilerB in NTDom2 should the need ever arise. The groups on FilerB would then be populated with users from NTDom2. This seems like it would preserve the overall security structure of the volumes being mirrored and not require any significant reconfiguration on NTDom2. -----Original Message----- From: Manish Anand Kinnerkar [mailto:Mak@wipro.co.in] Sent: Friday, June 27, 2003 2:48 AM To: toasters(a)mathworks.com Subject: RE: Question about mirroring This would be like a practical Disaster recovery scenario, I believe FilerB will have all shares of FilerA intact within itslef. After we make the mirror copy read write , the only problem we face now is that the acl's on the shares are useless , as the uids/domain do not exist.The authentication for this domain ceases to exist and thereby access is not possible at share level. FilerB cannot be a member of multiple domains at the same time, and will continue to reside in NTDom2 domain. Now it will be upto the administrator to manage these shares . Most logical thing to do would be to reassign them to new userids ( corresponding to old users of NTDom1) in current domain NTDom2 as NTDom1 has ceased to exist. Or create the NTDom1 domain all over again , but reassign share to the recreated userids. Experts on Windows Domain architecuture please comment on the same, coz frankly i'm not an expert in Windows :) regards, Mak. -----Original Message----- From: Holland, William L [mailto:hollandwl@state.gov] Sent: Thu 6/26/2003 6:24 PM To: 'toasters(a)mathworks.com' Cc: Subject: Question about mirroring Scenario: FilerA is installed at SiteA mirroring to FilerB at SiteB. Both are in Windows networks and both are using CIFS. SiteA is in NTDom1 and SiteB is in NTDom2. NTDom1 and NTDom2 are Windows NT domains, Active Directory is not implemented, and their is no trust relationship between the two NT Domains. FilerA has been using global groups and users from NTDom1 on its ACL's. SiteA along with FilerA ceases to exist for whatever reason. SiteB breaks the mirror and brings the volumes mirrored from FilerA online. Is it possible to access the files on those shares since NTDom1 no longer exists?
