More on NAS management

For an excellent overview of SANs and NAS read O'reilly's own bible type of book. Albeit somewhat outdated, the NAS management chapter does cover important aspects of managing a NAS system, and educates the reader on advanced topics such as CIFS oplocks.

How to quickly create a Solaris zone?

sh-3.00# zonecfg -z web1-zone
web1-zone: No such zone configured
Use 'create' to begin configuring a new zone.
zonecfg:web1-zone> create
zonecfg:web1-zone> set zonepath=/export/home/zones/web1-zones
zonecfg:web1-zone> set autoboot=true
zonecfg:web1-zone> add net
zonecfg:web1-zone:net> set address=10.1.70.233
zonecfg:web1-zone:net> set address=10.1.70.233/24
zonecfg:web1-zone:net> set physical=bge1
zonecfg:web1-zone:net> end
zonecfg:web1-zone> set pool=email-pool
zonecfg:web1-zone> verify
zonecfg:web1-zone> commit
zonecfg:web1-zone> exit
sh-3.00#

Install the zone:

sh-3.00# zoneadm -z web1-zone install

How to change a Solaris zone netmask?

So it's all in /etc/zones/.xml but they tell you not to touch it.

In here:
http://forums.sun.com/thread.jspa?threadID=5075758

They tell you to run this:

zonecfg -z email-zone
zonecfg:email-zone> remove net address=10.1.30.232
zonecfg:email-zone> add net
zonecfg:email-zone:net> set address=10.1.70.232/24
zonecfg:email-zone:net> set physical=bge0
zonecfg:email-zone:net> end
zonecfg:email-zone> commit
zonecfg:email-zone> exit

Use this format for new-ip to configure a specific subnet mask: 10.1.30.232/24.

Where to find ONTAP manpages

You can download the latest documentation set in zip format, and then install it right on a filer, and access it from the web.

Debugging security with sectrace

A new command called "sectrace" can help debug security problems (e.g. user cannot chown a file with NT ACL).

sectrace add -a -path /vol/software

will produce meesages such as these:

Sun Feb 1 13:10:52 IST [jim: sectrace.filter.allowed:info]: [sectrace index: 2] Access allowed because 'Synchronize, Read Attributes' permission (0x100080) is granted on file or directory (Access allowed by an explicit access control entry) - Status: 1:58720452:0:0 - 10.1.20.107 - NT user name: support\administrator - UNIX user name: root(0) - Qtree security style is NTFS and NT ACL is set on file/directory - Path: /vol/software/

Typically there is no need to use -a since you only want to debug DENY replies.

NetApp Filers Blog Reborn

Hi everyone!

It's been a while since I started this blog, and it's been quite fun to see its rapid growth from literally zero visits a month to over 80 a day.

I have decided to refresh the look & feel a bit, and make it more user friendly and useful.

I'll be happy to hear any comments on the content, and whether you'd like to see focused blog such as this one on competitive products.

Dr. Toaster.

The Filers Blog appears in TechONTAP
