Netapp cheat sheet

wagnerj — Thu, 03 Mar 2011 14:24:24 +0000

To show all of the aggregates on a filer and what disks are in them:

sysconfig -r

To show the disks in an Aggregate:

redhat rpm docs

wagnerj — Fri, 23 Apr 2010 14:07:19 +0000

quick reminder for me that all the readme and doc files for every installed program on a typical redhat system are in /usr/share/doc

in particular /usr/share/doc/initscripts* has skeleton a skeleton startup script.

Solaris 10 iso mount

wagnerj — Thu, 28 Jan 2010 20:14:39 +0000

Create the device

lofiadm -a /repo/pub/linux/redhat/rhel4.8/RHEL4.8-x86_64-AS-disc1.iso /dev/lofi/1

Mount it

mount -F hsfs -o ro /dev/lofi/1 /mnt/tmp1

remove the device

lofiadm -d /dev/lofi/1

opennms performance tweaks

wagnerj — Tue, 26 Jan 2010 14:35:44 +0000

To delete old events from the postgres db:

psql -U opennms opennms
DELETE FROM events WHERE eventid NOT IN (SELECT svclosteventid FROM outages) AND eventid NOT IN (SELECT svcregainedeventid FROM outages);

I modified the JAVA_HEAP_SIZE to 512mb in /usr/sbin/opennms

This will completely clear all events, alarms, outages, etc:

TRUNCATE alarms, alarm_attributes, notifications, usersnotified, outages, events;

SCSI device driver and bad Windows plug-n-play

wagnerj — Thu, 16 Jul 2009 12:54:38 +0000

After connecting an Overland NEO2000 to a Windows 2003 server and installing EMC networker. I had some very strange behaviors when I was just trying to label tapes. A few tapes would label, then things would just go bad. The most common error I recieved was:

Device/media error: read open error: the device file name
specified is unusable by CDI (drive status is Drive reports no
error − but state is unknown)

I also saw this one:

cannot set record size: block
size ioctl failed

In my case, this turned out to be a SCSI driver. Windows plug-n-play automatically added a SCSI driver for the LSI logic card in the server. When I replaced this driver with the one from LSI these errors were resolved.

NFS mount Solaris 10 -> Linux

wagnerj — Wed, 15 Jul 2009 20:12:28 +0000

Attempting mount a Solaris 10 client to a Redhat linux NFS server results in:

nfs mount: mount: /storage: Not owner

Apparently, linux doesn’t support nfsv4, which Solaris uses by default. I get around this quickly by:

mount -o vers=3 hostname:/mount /mount

enabling swat redhat 4.6

wagnerj — Mon, 06 Jul 2009 18:58:16 +0000

Install this RPM:samba-swat-3.0.25b-0.4E.6

chkconfig swat on

/etc/init.d/xinetd restart

I had to edit /etc/pam.d/samba and remove “/lib/security/” from both path’s in order for the root login to swat to work.

This didn't work, i think because it's clarion and not sun storage

Adding fibre storage to solaris 10

wagnerj — Fri, 26 Jun 2009 14:53:29 +0000

After binding & allocating a new lun for a Solaris 10 hosts:

For me, the lun shows up automatically in format. In this case, I just added a 197.00 GB Lun from a CX500. Output From the format command:

19. c3t500601683022431Ed4

/pci@7c0/pci@0/pci@1/pci@0,2/SUNW,emlxs@2/fp@0,0/ssd@w500601683022431e,4

20. c3t500601613022431Ed4

/pci@7c0/pci@0/pci@1/pci@0,2/SUNW,emlxs@2/fp@0,0/ssd@w500601613022431e,4

The Lun was previously unused, I chose the device, and wrote it’s first label.

The following are probably not necessary, but can’t hurt:

devfsadm -vC

disks

I am using emcpowerpath. Adding the devices to powerpath is:

powermt config

powermt save

To see the devices:

powermt display dev=all

Note. When using emcpower devices with zfs, if you add a lun to a zpool, format it first and put all of the space you want to use from the lun in partition0. Otherwise, it won’t actually add space to the zpool.
