How to find missing disks on Sun x4150 without reboot?
Hi, Here is the issue: There are 4 disks on this Sun x4150 system under Solaris 10, but only 1 disk can be seen by the OS. I've tried commands disks and devfsadm but not working. It's an important production server, so 'reboot -r' is not a choice.
I have a V490 that has couple internal disks attached to the same dual-port HBA card that I'm planning attach to the SAN for additional storage.
Would I sacrifice performance if I use the same HBA?
Is it better to throw in a new HBA instead? (1 Reply)
Hi,
I have SE 220R with 2 disks mirrored using SVM and running OS - solaris 9.
Because of performance issues on 220R I'd like to move the OS/application data to SF 280R. Having found that SF280R will only support Fiber channel disks, I am now wondering how to move complete data from SCSI... (3 Replies)

Hi, I was trying to upgrade firmware for this Sun x4150 from ELOM to ILOM. I did it under GUI ELOM Manager > Maintenance > Firmware Upgrade. It then showed 'Someone is upgrading firmware' and took forever. I believe its hung due to unknown reason (wrong file used?). I poweroff and poweron the... (4 Replies)
Hello world,
One of the servers, a Fedora one,rebooted today (Luckily, a testbox).
I tried to get the reason the server rebooted. After going through the messages, I think that the log entries just before and after reboot are missing.
Please below: (****** is the server name, for privacy... (0 Replies)
Hey everyone. First, let me start by saying I'm primarily focused on linux boxes, and just happened to get pulled into building two T5220's. I'm not super educated on sun boxes.
Both T5220's have 8 146GB 15k SAS drives. Inside the service processor, I can run SHOW /SYS/HDD{0-7} and they all come... (2 Replies)
Help Please!
I picked up a V440 and it has 4 disks. I installed Solaris fine to disk 3, but I cannot see the other disks in Solaris.
I have run probe-scsi-all from OBP and I see the other disks and they have names in devalias AFAIK. It's just in Solaris they do not appear. I have run... (6 Replies)

reboot
reboot(8) System Manager's Manual reboot(8)NAME
reboot - Restarts the machine
SYNOPSIS
/usr/sbin/reboot [-dlnq]
DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are
logged in, use the reboot command.
The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login
accounting file, /var/adm/wtmp.
The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically
checked. If the start-up activities are successful, the system comes up in the default run-level.
You must have root privileges to use this command. Using the -n flag can result in file system damage.
FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog
Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log
the reboot using syslog
EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l
This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system
abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.
