problem with my multipack (6 disks)

2007-12-25 11:53:00

Hello,

Thaks for all responses, sorry I did not list all helpers here, thanks

again!!

The part of solutions:

Switch the SCSI id of multipack to 7-14, then configure again, seem

works!?

I am very disappointed with Sun technical support,

First time they told me I need another Sbus card for my Ultra 2,

fortunately, lots helpers point out: no, I have wide SCSI on the Ultra

2, it can handle 15 devices.

now, I have two internal hard drives, one internal CD-ROM, one unipack

tape drive, I put the tape drive as last device on the SCSI chain and

put terminator (from multipack) on the tape drive (even it has

autoterminator), configured, seem works fine for a few hours, then

crash!

After disconnect SCSI devices, reboot, do fsck, then work fine.

I called Sun again,

1. I ask why I can not do probe-scsi, system will hang.

they told me a precedure, I tried:

ok> auto-boot? false

ok> reset

Stop-A at the middle of boot

ok> probe-scsi

This command may hang the system if a Stop-A or halt command has been

executed. Please type reset-all to reset the system before executing

this command.

Do you wish to continue? (y/n)y

System hung!!

Then I try:

ok> auto-boot? false

ok> reset-all

Stop-A at the middle of boot

ok> probe-scsi

This command may hang the system if a Stop-A or halt command has been

executed. Please type reset-all to reset the system before executing

this command.

Do you wish to continue? (y/n)y

System hung again!!

2. I ask why my system crash with multipack, they told me I need put

multipack on the last of SCSI chain without terminator.

I did not try this, because I read the manual again:

Wide Host-Tape Drive or CD-ROM

        If a SPARCstorage Multipack unit and SPARCstorage UnitPack unit are

chained on a single SCSI bus, the UniPack unit must be last on the

chain.

Installing a Terminator

        Each SPARCstorage MultiPack drive enclosure come with an external

single-ended terminator. Install the terminator on the unused lower SCSI

connector of a SPARCstorage MultiPack unit after you have connectd it to

the host or another SPARCstorage MultiPack unit.

So, they really confuse me, Anyone can clear out this for me, please!!

Thanks again!!!
