Hi Geoff, 1) Please use the FilerView to remove the filer nodename. 2) Click Right-Click on My Computer - manage - disk management Write Signature -> Format and assign the letter (e.g. N:\ = NetApp) If you have any questions please let me know.

iSCSI HOWTO question
by Geoff Hardin 08 Jan '04

08 Jan '04

I am new to the SAN environment, and most especially to the iSCSI way of doing things. I have the iSCSI protocol enabled on my filer, and I have the Microsoft iSCSI initiator downloaded and installed on my PC. From the filer, I have created a couple LUNs on my filer, I have created igroups, mapped the LUNs to the igroups, set the create_ucode option to on, and started the iSCSI service. On the Windows system, I have added the target portal, logged on, and I can see an active session. I think I have all the basics under control. What I can't seem to figure out is how the LUNs now show up as being somehow connected to my Windows computer. I'm sure I've missed something, but I can't figure out what. I've tried reading the "ONTAP SysAdmin Block Access Management Guide" and working through the examples step by step, still to no avail. Some details: Host (initiator): Windows 2000 ONTAP version 6.4.3 toaster> iscsi show adapter Adapter: iswta Slot: N/A Description: NetApp Software Implementation Status: Online Target Portal Groups: portal group 1: inet 192.168.1.3 port 3260 toaster> igroup show windows-igroup0 (iSCSI) (ostype: windows): iqn.1992-08.com.netapp:sn.123456789 toaster> lun show -v /vol/vol0/iscsi/lun0 10.0g (10742215680) (r/w, online, mapped) Comment: "iSCSI test lun0" Serial#: HPlwFYo6bJoZ Share: none Space Reservation: enabled Multiprotocol Type: windows Maps: windows-igroup0=0 /vol/vol0/iscsi/lun1 10.0g (10742215680) (r/w, online, mapped) Comment: "iSCSI test lun1" Serial#: HPlwFYo6bQDV Share: none Space Reservation: enabled Multiprotocol Type: windows Maps: windows-igroup0=1 toaster> iswt interface show Interface e0 enabled toaster> iscsi nodename iSCSI target nodename: iqn.1992-08.com.netapp:sn.123456789 Any help would be greatly appreciated.

Tom, Does this apply to sharing out to netgroups and IP ranges as well? -Mark -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Haynes, Tom Sent: Tuesday, January 06, 2004 9:48 AM To: Jerry Cc: toasters(a)mathworks.com Subject: Re: exports What happens if someone reuses the host name after a month? Say you have an export: /vol/payroll -access=george:harry:arnold:fred,rw=harry:arnold:george,root=arnold:geor ge And you retire arnold. You never change the export or there is a new admin who doesn't know to look at the export lists. Several times since the old arnold was retired, "exportfs -a" was run. Warning messages were printed to the console about no arnold being available. We don't let arnold have rw or root permissions, but due to the nature of -access, we have to leave the string "arnold" in that list, meaning that the client arnold would still have read/only access. Someone brings up a general purpose server on the network and being a huge fan of TV pigs, goes immediately for the available host name of arnold. The new arnold is immediatley able to get read permissions on /vol/payroll and several salaries get shared. A new volume gets created on the filer and someone reruns "exportfs -a". Now arnold is able to write as root to the payroll volume. In retrospect, a warning would have been nicer, wild security example aside, but at the time we were trying to patch the exports code and not redesign it to a new specification. We redesigned the exports code in 6.5 and as we no longer preload host IPs for -rw= and -root=, we do not detect that a host is no longer being resolved to IP. As a result, we do not throw away the entire export rule. The flip side is that arnold can still run amuck through your payroll, so check your export lists when you retire a secure server name. ;> > Has anyone seen where exporting a filesystem after a > reboot fails because exports has the name of a host > that no longer exists? > > My co-worker had this problem and support said this is > by design.

RE: Legato Networker 7.1 and NDMP backups
by Garavito, Donald, CTR, OSD-ATL 07 Jan '04

07 Jan '04

We ran into this problem with Syncsort Backup Express. Starting with 6.3 Data ONTAP supports NDMP v4 and sets this as the default. Applications are supposed to negotiate down to the appropriate level for communications, but most backup software packages do not. Use command line "ndmpd version 3" to set the ndmp max version level to 3 (which is what most backup software now support) and your problem should be solved. The main reason for failure is that the filer (ndmp v4) and backup server (ndmp v3)cannot properly communicate and when the first tape is full, filer waits for backup server to perform media controller (picker) commands to change tape. Unfortunately, the backup server is waiting for filer to report that the tape drive is full, needs to be unloaded and new tape mounted. The vicious circle, one waiting for the other until filer finally gives up and times out with tape failure.

This only happens with our NDMP backups of the netapp and I was wondering if anyone here had the same problem? We've been working with our Legato support for months and haven't been able to rectify the problem, so I'm going to downgrade to version 6.1.4 as that used to work fine. Bit of a last resort option, but we've not had reliable backups for months and we're at our wits end. Any suggestions before I do this?

No fancy editing, but you can read the file with rdfile and the cut-n-paste the corrected version with wrfile. wrfile is very much like the unix `cat` command, except ^C is exit instead of ^D. ^D logs you out of the filer, but doesn't save the file. rdfile and wrfile are advanced mode commands, so use at your own risk, etc. John

exports
by Jerry 06 Jan '04

06 Jan '04

Has anyone seen where exporting a filesystem after a reboot fails because exports has the name of a host that no longer exists? My co-worker had this problem and support said this is by design. This proved to be problematic for us when we had a filer reboot and it failed to export some filesystems because some host had been removed a long time ago. Considering the reliability of the filer, it's reasonable that some hosts in the export list might disappear, I'd rather see this as a warning than something that breaks the filer's ability to serve volumes. After all, nothing a client does should break a server, general rule. Jerry __________________________________ Do you Yahoo!? Yahoo!
