Solution Type Technical Instruction Sure Solution 1004999.1 : How to reset date on Sun Blade[TM] 100/150 instead of hardware replacement
PreviouslyPublishedAs 207010 Description SB100/SB150 cannot boot properly after the date is set to year 2038. Only after resetting the date, the system could boot up correctly. This article illustrates an alternate way to reset date when system is unable to boot due to the date problem. Steps to Follow SB100/SB150 cannot boot properly after the date is set to the year 2038. During boot, boot -s, boot cdrom -s or boot net -s, the following error messages would appear and the boot cycle would stall. ok date 01/23/2038 18:01:39 GMT ok boot net -s cat: Cannot stat stdout /sbin/rcS: /etc/vfstab: cannot create INIT: Cannot create /var/adm/utmpx INIT: failed write of utmpx entry:" " INIT: failed write of utmpx entry:" " INIT: SINGLE USER MODE /dev/fd/3: /dev/fd/3: cannot open ENTER RUN LEVEL (0-6, s or S) [2]:s INIT: SINGLE USER MODE /dev/fd/3: /dev/fd/3: cannot open ENTER RUN LEVEL (0-6, s or S) [2]: The usual way of resetting date is to use the /usr/bin/date command from Solaris[TM], since the system cannot boot up properly, this method is not possible. Note that the Time of Day (TOD) information is stored in NVRAM, removing the battery CR2032 if present would not help. Replacing the NVRAM might solve the problem. However, a more cost-effective work-around is to create an RCscript such that the system can reset the date in the init phase of the boot process. Below are steps to reset the date back to normal using another machine to edit the RCscript. 1. Put the boot disk of the problem machine into a good machine as a NON boot drive. Do note that the harddisk interface on the SB100/SB150 is IDE (ATAPI) type. 2. Mount the boot disk of the problem machine to a mount point. Example: (c0t1d0s0 is the problem machine's boot drive) # mount /dev/dsk/c0t1d0s0 /<mount point> 3. Create the following RCscript in <mount point>/etc/rcS.d directory. --/etc/rcS.d/S99date-- #!/sbin/sh date 0401202004 -------------------------- Change the permission of the file into 744 to make it executable. # chmod 744 /etc/rcS.d/S99date 4. Unmount and remove the problem machine boot disk from the good machine. 5. Put the problem machine boot disk back into the problem machine. *** Boot SINGLE USER mode only *** to prevent time sensitive applications from starting up, if present. Once the machine boot up successfully, REMEMBER to REMOVE the S99date RCscript. Finally fine-tune the date to the accurate date/time again in Single User mode, before proceeding to Multi-User mode.
