Attaching disks without Powerpath

Mike,

Confirm from Navisphere Manager how many paths you have got logged in and connected for this particular server. Remember that without PP you can only have one single path to a LUN¿
Also use Diskpart to check and if necessary to modify the readonly, hidden and nodefaultdriveletter volume attributes as per below example:

C:\diskpart

DISKPART>list

DISKPART>list disk

DISKPART> select disk 4

DISKPART> detail disk

PowerDevice by PowerPath
Disk ID: 9F0B09CD
Type : FIBRE
Bus : 0
Target : 1
LUN ID : 3

Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 5 M SQL 2005 MD NTFS Partition 10 GB Healthy

Verify the Disk ID is set correctly. Note the Volume number as well and use it in the next command:

DISKPART> list volume

DISKPART> select volume 5

DISKPART> list partition

DISKPART> select partition 1

DISKPART> detail partition

DISKPART> detail volume

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
* Disk 4 Online 10 GB 0 B

Readonly : No
Hidden : No
No Default Drive Letter: No
Shadow Copy : No

If any of the ReadOnly, Hidden, or No Default Drive Letter are set to yes, clear them with the follow command:

DISKPART> att vol clear readonly hidden nodefaultdriveletter

Volume attributes cleared successfully.

DISKPART>exit

I hope this helps
Carl

I hope you aren't using that 300GB disk for anything important. With only a single path available to you there are lots of things that could cause a SAN outage for this host!

calle,

I will give this a shot thanks.

Mike

Kelleg,

This worked thanks!
