Replacing a Disk Module
65
Removing a Failed Disk Module
You can replace a failed disk module while the storage system is powered
on. If necessary, you can also replace a disk module that has not failed, such
as a module that has reported many “soft” errors. When replacing a module
that has not failed, you must do so while the storage system is powered up
so that the SP knows the module is being replaced.
Caution:
To maintain proper cooling in the storage system, never remove a
disk module until you are ready to install a replacement. Never remove
more than one disk module at a time.
To remove a disk module, follow these steps:
1.
Verify that the suspected module has actually failed.
Caution:
If you remove the wrong disk module, you introduce an
additional fault that shuts down the physical disk containing the failed
module. In this situation, the operating system software cannot access
the physical disk until you initialize it again.
2.
Read “Setting Up the Workplace for Replacing or Installing Disk
Modules,” earlier in this chapter.
3.
Locate the disk module that you want to remove; see Figure 5-2 if
necessary.
4.
Position the new disk module in its antistatic packaging within reach of
the storage system.
5.
If you are using an ESD wrist strap, attach its clip to the ESD bracket at
the bottom of the storage system. Figure 5-3 shows where to attach the
clip on a deskside storage system.
