How to find whether a disk is hot swappable

[Manoj1]

Hi All,

How to find whether a disk is hot swappable on HP-UX PA-RISC and Itanium ?

Thanks,
Manoj

check the server HW manual.

Hi,

Please check in server manual and also disk

also check through ioscan -fnkC disk command and find disk model no and check this hot swapable or not

[Torsten.]

It depends on the hardware (server or enclosure model).


What model do you have?

vgdisplay -v

And what in heaven's name is vgdisplay supposed to tell us about whether a disk is hot swappable or not???????

"vgdisplay -v "

With this you cannot see if a disk is or is not hot-swappable......

[Torsten.]

IMHO as long as you don't have really old hardware (e.g. K-class, V-class, some D-class models, e-class and older), the internal disks should be hot pluggable.

Tell us about your hardware and we will see ...




BTW, there is NO command that tells you if a disk is hot pluggable or not.

It applies here.

Some things you just have to do by looking.

Manoj1,

It depends sir. But possible by (1) knowing your HW model and 2, beoming familiar with ioscan output.

With "model" command - it will give you the class and make of your machine.

For RP series machines (N-Class and rp series) - the norm is those have internal disks - usually 18, 36, 73 GB ones. Sometimes those will be connected to external disk enclosures. And over the years -- generally my hint the disk is hot-swappable and hot-pluggable is if the disks are HP types and sized 18, 36 or 73 Giggers. You can also discern this by looking at ioscan output for disks and noting the connection point/bus/hw-path.


For older RX (Itanium) RX series -- the same holds true as described above.

For newer Itaniums -- rx6600, rx3600, rx2660 -- those will likely have internal RAID controllers (common with Proliants) which you can check via "sasmgr" command.

Hello Manoj,

Most of the disks are hot swappable these days,
but you need OLAR patches for the same,

Both command and kernel components are required to enable LVM OLR:
â ¢ For HP-UX 11i version 1, install patches PHKL_31216 and PHCO_30698 or their superseding patches.
â ¢ For HP-UX 11i version 2, install patches PHKL_32095 and PHCO_31709 or their superseding patches.
