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
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.
