RE: Command to Sanitize NetApp Filer?
by Hart, Paul 01 Feb '05

Mike you should try disk sanitize start [-p pattern1|-r [-p pattern2|-r [-p pattern3|-r]]] [-c number_of_cycles] disk_list disk sanitize start [-p pattern|-r [-p pattern|-r [-p pattern|-r]]] [-c cycles] disk_list Used to start the sanitization process on the disks listed. The -p option defines the byte pattern(s) and the number of write passes in each cycle. The -r option may be used to generate a write of random data, instead of a defined byte pattern. If no patterns are specified, the … [View More]

RE: Switching from NIS auth to Windows Domain
by Kazsuk, Tim 01 Feb '05

If the user names are the same on the Windows side and the Unix side, regardless of what Domain those users are a part of, you shouldn't have any issues with the drive mappings. As defined in the "System Administration - File Access Management Guide for Data ONTAP 6.5" pg.93, these are the steps taken when a CIFS session is requested: - It searches the /etc/usermap.cfg to see whether an entry matches the user's Windows domain name and user name. - If an entry is found, Data ONTAP uses the … [View More]UNIX name specified in the entry to look up the UID and GID from the UNIX password database. If the UNIX name is a null string, Data ONTAP denies access to the CIFS user. - If an entry is not found, Data ONTAP converts the Windows name to lowercase and considers the UNIX name to be the same as the Windows name. Data ONTAP uses this UNIX name to look up the UID and GID from the UNIX password database. If that doesn't work, you also might want to look into setting up the usermap.cfg file in such a way that will work in your environment.

We started out with NFS on Unix and added CIFS access later. We have about 30,000 user accounts. We have always used NIS authentication for CIFS so that folks have the same password on Unix and CIFS. But we have been unhappy with the passwords going over the network in clear text. We have finally gotten funding for enough Windows client licenses to give all our users accounts in a Windows domain, so we want to switch our filers to Windows domain auth. This is going to cause us a serious user education problem. Currently it does not matter what domain a CIFS user specifies because the domain name is ignored when mapping a to a NIS user. For example, BOGUS\fred maps to "fred" and MYDOM\jane maps to "jane", etc. Right now when "fred" does a "map network drive" he just enters "fred" for his username. His PC supplies the windows domain, whatever that may be. Some folks login to local departmental domains. Some do local Windows logins, etc. Right now that doesn't matter because the filers ignore the domain name when mapping to a NIS username. But that will suddenly change when we switch to Windows domain auth. Fred will suddenly be required enter "ESERVICES\fred" instead of just "fred". Does the filer have any option where it "knows" that no matter what domain name the user supplies, in his heart of hearts he really means "ESERVICES" ? That would save us an awful lot of calls at our help desk when we cut over. By the way, we don't know in advance what domain name a user may supply. Many of them appear to be whatever name the user gave his PC. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support [View Less]
