Hi. Due to a coworker moving on I've just inherited administration of several machines, including a T5120 1U server
running Solaris 10 that (as if on cue) is now freezing during boot.
I am not normally a sysadmin at all: I administer my personal Linux machine at home, and admin'd various Unix-ish machines
in the early 90s, but I haven't handled admin responsibilities for quite some time and know next to nothing about what's
different administering Solaris from other Unixes. So the first help I could really use: a web resource for educating myself
on relevant admin stuff. I've googled things like "solaris administration primer" without much success.
The second thing I could use: advice on how to proceed with my problem T5120. With much effort figuring out the
T5120 Administration Guide available online from Oracle, I was finally able to get a system console using an RS-232
connection on a nearby Linux server. Through the ILO system, I was able to watch the boot process, see that it
gets through the power-on self tests OK, starts to boot SunOS off of disk, gets through the first few banner lines
of the OS boot, shows me a twirling cursor (slashes and dashes), and then freezes. The thing that occurs to me
to do next, from my Linux experience, is to boot off the CDROM to get a shell; but assuming that works OK,
I'm not sure what I'd check once I got there.
Thanks for any help/advice with either of these issues.
Particularly ch.14 May be useful. ( there again it might be dangerous).
One gotcha is if you are working with svm mirrored root/boot disks and you end up applying changes to one and not the other .... corrupion may occur ... you are at risk of that if you boot from cdrom unless you unmirror the disks.
There's no overall primer I can think of. For solaris 10 the OpenSolaris Bible (Bible (Wiley)) possilby contains a lot of good stuff and relatively readable ..... it is opensolaris not solaris 10 so a few things are a half way house between solaris 10 and 11 ... but it probably gives a good overview .... but it it's not totally authorative and could occasionally misleading. ISBN-13: 978-0470385487.
I also note: Solaris 10 System Administration Essentials (Solaris System Administration) : Publication Date: 23 Nov 2009 | ISBN-10: 013700009X | ISBN-13: 978-0137000098 | Edition: 1 ... but I've never used it myself.
Also: Calkins ISBN-13: 978-0789737908 and ISBN-13: 978-0789738172 might also be useful. I'd get the hardcopy with the cdrom.
Be repard any of above may disappoint, and not be what your're looking for. so read reviews. The kindle editions may have poor indexing.
This is just really a set of places to look.
You might also find it useful to get auto-boot? set to off so the thing stops at the OBP OK prompt:
