Hi Stephen,

Read the attached document and follow the steps.

Good luck.

rariasn,
sometimes the disk is just failing but not completely failed, could I consider it failed and follow your method?

If this is not a hardware mirror, you need to redirect the new to the old device file after replacement, e.g.

# sasmgr replace_tgt -D /dev/sasd0 -q old_dev=/dev/dsk/c1t4d0 -q new_tgt_hwpath=0/4/1/0.0.0.11.0

(adjust the values to your configuration)

Torsten,
is it necessary to follow your idea at 11.23? i consider REPLACING the disk would reuse the device file.

The SAS disk will always get a new device file, so you need to adjust it before you can use the "old" configuration.

Torsten,
can I just use the new device file when
#pvchange -a n
#vgcfgrestore -n vg00
but not using your idea?

regards
Stephen

[stephen peng]

sorry, it should be
#pvchange -a n s2
#vgcfgrestore -n vg00 s2

[Torsten.]

No, all your existing configuration contains the old device file.
