Google Now on Tap doesn't turn on

if Google Now on Tap (Android Marshmallow or better) doesn't turn on or turns on, but quickly turns off, then you probably have an account on google apps.  Your domain administrator needs to do the following (referenced from:  https://productforums.google.com/d/msg/websearch/hLazcAVC5MA/0kV53XllqFkJ)

open admin console (admin.google.com), then choose Apps, then Additional Google services. Then disable filter "Top featured services" near the top half of the page. This is important (!). When you turn filter off you will see a long list of google services, you have to find "Web history" and turn it on.

swpackage error / copy depot bundle to file

ERROR:   The fileset XXXXX will not fit on the tape

         "/tmp/XXX.depot".  The fileset requires 4249089 Kbytes of

         tape space, but the tape provides only 1298828 Kbytes.  The

         fileset requires a larger tape.

 

Fix by:

swpackage -s /source/dir -x allow_large_serial_depot=true -x media_capacity=50000 -x target_type=tape @ /ignite/r11.depot bundle/package/etc

media_capacity=larger than depot file

it can't deliver local mail since the /var/mail didn't exist in this case....

/var/mail needs to be created and bin:mail ownership and 775 permissions

ssh doesn't work after ignite recovery

ssh connections have errors after doing an ignite recovery. If the
following shows up in syslog:
sshd[14702]: error: openpty: No such file or directory
sshd[14704]: error: session_pty_req: session 0 alloc failed

check another server with ssh working using lsof and you'll find
/dev/ptmx reference:
sshd 22391 root 7u STR 156,0 0t41177 2935 /dev/ptmx->ptm

re-create the device file using mknod to this:
crw-rw-rw- 1 root root 72 0x00009c Nov 27 04:23 /dev/ptmx


Also /dev/klog was missing (as seen in syslog) after the ignite recovery:
crw------- 1 bin bin 189 0x000000 Dec 22 2010 /dev/klog

headless ubuntu / linux

if you are running a headless ubuntu / linux server and have no remote
console at all and it's important for the OS to boot without requiring
interaction make sure you do this:

http://www.linuxquestions.org/questions/linux-newbie-8/grub-not-working-default-highlighted-but-timeout-doesn't-auto-select-4175490182/

set GRUB_RECORDFAIL_TIMEOUT=2 (or whatever timeout you want). and of
course, run update-grub.

This will prevent it from sitting / hanging at the grub menu because
of a power failure or whatever.....

avio_stor and avio_lan on hpvm guest

slow network performance was fixed by changing the adapter type from
lan to avio_lan.


Here's a quick way to do it:

## where 0,0 is the bus,dev (found from hpvmstatus –P $vm_name )of
the disks -- may list multiple -m

hpvmmodify -P VM -m hba:avio_stor:0,0



## where 0,1 is the bus,dev (found from hpvmstatus -P $vm_name) and
lan2 is the vswitch name

hpvmmodify -P VM -m network:avio_lan:0,1:vswitch:lan2
