Miscellaneous Issues Power to the Snap Server Is Unexpectedly Cut Off Due to a Power Outage Adaptec recommends that you use an uninterruptible power supply (UPS) with the Snap Server. If you did not have a UPS attached to the server at the time of the power outage, do the following: 1 On Snap Servers with no on/off switch, remove the power cables. On SANbloc S50 and SD30SA, turn off the power switches on the back of the unit. 2 Once the power is restored and stabilized, turn the power supplies back on and reboot the server. Once the Snap Server boots, it begins resynchronizing the RAID(s) if necessary. You can use the server during the resynchronization, but performance will be a little slower than normal. Do not remove drives, however, while the server is resynchronizing the RAID. The Server Is Not Responding to File Requests or Configuration Commands Call your Snap Server technical support representative. Problems with Cable Arm on the 18000 with a SCSI Cable Attached The size of the connector on an attached SCSI cable may prevent the 18000 from fully withdrawing into a rack when the cable management arm is attached. To resolve this problem, remove the cable management arm. You Have Problems Seeing the Tape Library Tape Device, Not the Robotic Arm When you have problems seeing the actual tape device rather than the robotic arm, it is most likely due to the Tape Loader being configured for Sequential Access. Change the Tape Loader to Random or Mixed Mode. The Admin Password to the Administration Tool Is Not Available You can perform a limited reset to defaults, which includes the admin password (as described in "Performing System Resets Without Network Access" on page 179); then use the Administration Tool to set a new password. The Snap Server 510, 520, 550, 650, or 18000 LCD is Flashing A flashing LCD indicates a server panic. In some cases, rebooting the server may solve the problem. However, if this condition occurs more than once, try resetting the system as described in "Performing System Resets Without Network Access" on page 179. Appendix C Troubleshooting Snap Servers 185

Miscellaneous Issues

Troubleshooting Snap Servers
185
Power to the Snap Server Is Unexpectedly Cut Off Due to a Power Outage
Adaptec recommends that you use an uninterruptible power supply (UPS) with the
Snap Server. If you did not have a UPS attached to the server at the time of the
power outage, do the following:
1
On Snap Server
s
with no on/off switch, remove the power cables. On SANbloc
S50 and
SD30SA, turn off the power switches on the back of the unit.
2
Once the power is restored and stabilized, turn the power supplies back on and
reboot the server.
Once the Snap Server boots, it begins resynchronizing the RAID(s) if necessary.
You can use the server during the resynchronization, but performance will be a
little slower than normal. Do not remove drives, however, while the server is
resynchronizing the RAID.
The Server Is Not Responding to File Requests or Configuration Commands
Call your Snap Server technical support representative.
Problems with Cable Arm on the 18000 with a SCSI Cable Attached
The size of the connector on an attached SCSI cable may prevent the 18000 from
fully withdrawing into a rack when the cable management arm is attached. To
resolve this problem, remove the cable management arm.
You Have Problems Seeing the Tape Library Tape Device, Not the Robotic Arm
When you have problems seeing the actual tape device rather than the robotic arm,
it is most likely due to the Tape Loader being configured for Sequential Access.
Change the Tape Loader to Random or Mixed Mode.
The Admin
Password to the Administration Tool Is Not Available
You can perform a limited reset to defaults, which includes the admin password (as
described in “Performing System Resets Without Network Access” on page 179);
then use the Administration Tool to set a new password.
The Snap Server 510, 520, 550, 650, or 18000 LCD is Flashing
A flashing LCD indicates a server panic. In some cases, rebooting the server may
solve the problem. However, if this condition occurs more than once, try resetting
the system as described in “Performing System Resets Without Network Access” on
page 179.
