Hi all, I would like to backup an NFS system (from a Network Appliances filer) to a local tape drive (with multi-volume), via Solaris 8 system, which command is better ? I have try to make this backup with ufsdump, but I have error : root@server:/tmp# ufsdump 0uf /dev/rmt/0cn /mnt/filer/ DUMP: `/mnt/filer' is not on a locally mounted filesystem DUMP: The ENTIRE dump is aborted. root@server:/tmp# Thanks, Laurent

iSCSI MPIO Support/Experiences
by Alan.McLachlan＠didata.com.au 28 Oct '04

28 Oct '04

Hi Evan, MPIO is required for load balancing and failover if you are using the Intel iSCSI HBA (TOE card). Intel do not provide their own teaming driver for this card. If you are using the MS software iSCSI initiator with regular 1000BaseT Ethernet NIC's, you can use the regular teaming drivers that come with your NIC's. i.e. for Intel Pro1000 NIC's use the "Adaptive Load Balancing" driver to create a virtual NIC from the two physical NIC's, then bind the Microsoft software iSCSI initiator to the virtual NIC. Using MPIO and the iSCSI HBA's is a more expensive solution (due to the cost of the HBA's), but worth considering if you feel you need to minimise CPU overhead on your application host. regards, Alan McLachlan ___________________________________ Solution Architect - Data Centre Solutions Dimension Data Australia Alan.McLachlan(a)didata.com.au Tel. +61 (0)2 61225123 Fax +61 (0)2 62486346 Mobile 0428 655644 ----- Forwarded by Alan McLachlan on 28/10/2004 09:52 AM ----- "Evan Battle" <ebattle(a)Intellimark-IT.com> Sent by: owner-toasters(a)mathworks.com 27/10/2004 11:49 PM To: <toasters(a)mathworks.com> cc: Subject: iSCSI MPIO Support/Experiences <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />I have seen conflicting information on the site regarding MPIO support. The SnapDrive/Ontap Compatibility Matrix shows iSCSI is not supported for MPIO, however a press release dated August 23, 2004 indicated that NetApp does have an MPIO solution for the MS implementation of iSCSI. Does the SnapDrive MPIO driver now work w/ iSCSI? Is this dependent upon using the MS iSCSI initiator and not an iSCSI HBA? Also, do any of you have any experience implementing a MPIO iSCSI solution? If so, what have been your experiences.

RE: spares disks no more equivalent from one filer to another one
by Derek Lai 26 Oct '04

26 Oct '04

The ability to take spare disks from system to system used to be true but it broke a while ago. There is also the issue of the DS14 MK1 vs. MK2 shelf issue. The old drives that you have in DS14 MK1 system can not be inserted into DS14 MK2 shelves either. But that is progress. I think NetApp in general tries pretty hard to be backward compatible where they can. The new "Universal" keyed drives on the MK2 shelves can be inserted into MK1 shelves as well. Are you saying that you can zero a disk on a 6.5 system to be used in a 6.4 system? I will not work either with just a simple spares_zero command (which only zeros a spare). The problems is DataOntap will refuse to put the drives into the system. You have to completely rewrite the label on the drive. To do so requires that you reboot and drop into the maintenance menu and then pick the option to re-label the drive. Anyone know why this is the case? I can't think of a good reason for doing so. The rationale is suppose to be that once you upgraded the system to 6.5, you need to revert and do extra work to go back to running 6.4. But this is a pain when you maintain a large number of filers and have to now keep track of one other unnecessary thing. I think at a minimum NetApp should do a better job of proactively telling the sys admins so they don't get surprised at the last minute. If we know about these sort of things we can plan ahead and avoid the problems.
