ioinit -c command

[EJ Stremler]

We have an issue that a system was not rebooted for a while, then a port on the SAN was moved for a particular tape drive. Now ioscan shows NO_HDW for this tape drive. On the SAN end, the tape drive is still zoned to the host. We tried ioscan -f and insf -e and ioscan still shows NO_HDW. Without re-booting the system, can we do an ioinit -c to create a new /etc/ioconfig file, so we can possibly recognize the tape drive again? Would this be safe to do?

Ed,

I don't think you can perform this without a reboot.
Also keep in mind it can re-number your instance numbers.

Instance number already exists for a given class. Use rmsf to
remove the existing instance number, then retry.

Hi,

Normally when you disconnect and connect the device back it should get CLAIMED in ioscan automatically.

Please check the ZONE config in SAN, is it a HARD ZONE / SOFT ZONE ?

Check in terms of any changes WWN ( of port) or PID&DIDs.

With Regards,

Siva.

Hi Ed,

If you moved the tape drive to an other port and your zoning is OK, the tape drive should appear with another device file

Try this
ioscan -fnC tape
insf -e
ioscan -funC tape

If you can see the tape then the zoning is OK. Afterwards you can modify the device files if you would like
