sedutil for SAS drives has inconsistent behavior for --scan and --printDefaultPassword

[ganeshram93]

I tried the sedutil-cli for multiple SAS drives and I see inconsistent output every time I run it.

Issue 1:
Command used: sedutil-cli --scan
Output 1: (expected output)
root@ssd-Z270X-Gaming-K7:~/ssd/sedutil_backup# ./sedutil-cli --scan
Scanning for Opal compliant disks
/dev/sda E xyz xyz
/dev/sdb No
/dev/sdc No

Output 2: (failed)
root@ssd-Z270X-Gaming-K7:~/ssd/sedutil_backup# ./sedutil-cli --scan
Scanning for Opal compliant disks
/dev/sda No
/dev/sdb No
/dev/sdc No

Output 3: (failed)

/dev/sdb No
/dev/sdc No

Issue 2:
Command used: sedutil-cli --printDefaultPassword /dev/sda

Output 1: (failed)
root@ssd-Z270X-Gaming-K7:~/ssd/sedutil_backup# ./sedutil-cli --printDefaultPassword /dev/sda

However, when I tried with NVMe drives, it works well.
Is this a known issue / is there a fix available?

Closing it.
It was an HBA adapter issue.
