Sun Fire X4500 and X4540
Contents |
Hard disks
The Sun Fire X4500 has 48 SATA disks on standard SATA controllers (no RAID). It is hot swappable, and the systems are racked to allow them to be fully extended out on their rails while remaining powered on with network connectivity.
The OS drives are the two leftmost at the front (controller 5, disks 0 & 4), no other drives show in the BIOS during post.
The disks are (currently) configured as a RAID-Z pool in 9 striped sets of 5; total space is ~8TB. It's mounted at /export.
Replace a disk
Note: untested!
To replace c7t6d0:
root@ms2:~# zpool offline export c7t6d0 Bringing device c7t6d0 offline root@ms2:~# cfgadm -l | grep c7t6d0 sata5/6::dsk/c7t6d0 disk connected configured ok root@ms2:~# cfgadm -c unconfigure sata5/6::dsk/c7t6d0 Unconfigure the device at: /devices/pci@2,0/pci1022,7458@8/pci11ab,11ab@1:6 This operation will suspend activity on the SATA device Continue (yes/no)? yes
(now replace the disk)
root@ms2:~# cfgadm -c configure sata5/6::dsk/c7t6d0 root@ms2:~# zpool replace export c7t6d0
OS setup
This is how the OS (Solaris) is set up on the image servers (ms1/ms2).
Solaris 10 5/08 (Update 5) is installed. Docs are at http://docs.sun.com/.
Disks c5t0d0 and c5t4d0 (the two left-most at the front) are mirrored for the root slice and swap. (Reference: Solaris Volume Manager Administration Guide)
For software not included in Solaris, we use the Toolserver software repository. This is in SVN at /trunk/tools/ts-specs. These are RPM spec files that can be built into Solaris packages with pkgtool.
$ pkgtool -v build-only --download TSwhatever.spec $ su # pkgadd -d $HOME/packages TSwhatever
Most software from this repository installs into /opt/ts. PHP is in /opt/php. (Config file: /etc/opt/php/php.ini)
Service management is done with the Solaris SMF (Service Management Framework) (Reference: Solaris Administration Guide)
List services:
# svcs -a
Find out why a service is in 'maintenance' state instead of 'online':
# svcs -vx <name>
Disable a service:
# svcadm disable <name>
Enable a service:
# svcadm enable <name>
Disable a service but leave it enabled on the next boot:
# svcadm disable -t <name>
Enable a service but leave it disabled on the next boot:
# svcadm enable -t <name>
Service name can be abbreviated, e.g. 'lighttpd' instead of 'svc:/network/lighttpd:lighttpd'.
Lighttpd is the same as amane. Config: /etc/lighttpd/lighttpd.conf. It's built from TSlighttpd in the Toolserver repo.
For OS upgrades and patching, Live Upgrade should be used. This creates copies of the running OS. List current LU boot environments:
root@ms1:~# lustatus Boot Environment Is Active Active Can Copy Name Complete Now On Reboot Delete Status -------------------------- -------- ------ --------- ------ ---------- s10b yes no no yes - s10a yes yes yes no -
Re-initialise 's10b' (the inactive environment):
# lumake s10b
List patches:
# smpatch analyze
Apply patches to s10b and reboot:
# smpatch update -b s10b # luactivate s10b # init 6
Lights Out Management
The Sun X4500 uses iLOM.
The standard administrative account is root and the default password is changeme.
Common actions
Changing the root password
set /SP/users/root password=password
Serial console
start /SP/console
Power cycle
Reset:
reset /SYS
Power Off:
stop /SYS
Power On:
start /SYS
End the session with Esc-(
Setting an IP address for the network port of LOM
Login to the LOM over serial and run the following:
cd /SP/network set pendingipaddress=ipaddress set pendingipnetmask=255.255.0.0 set pendingipgateway=10.1.0.1 set pendingipdiscovery=static set commitpending=true
Once that is done, you should be able to connect over the management IP if it is plugged into the management network.
